Pertti Mattila
Pertti Esko Juhani Mattila (born 28 March 1948) is a Finnish mathematician working in geometric measure theory, complex analysis and harmonic analysis. He is Professor of Mathematics in the Department of Mathematics and Statistics at the University of Helsinki, Finland. He is known for his work on geometric measure theory and in particular applications to complex analysis and harmonic analysis. His work include a counterexample to the general Vitushkin's conjecture and with Mark Melnikov and Joan Verdera he introduced new techniques to understand the geometric structure of removable sets for complex analytic functions which together with other works in the field eventually led to the solution of Painlevé's problem by Xavier Tolsa. His book ''Geometry of Sets and Measures in Euclidean Spaces: Fractals and Rectifiability'' is now a widely cited and a standard textbook in this field. Mattila has been the leading figure on creating the geometric measure theory school in Finland a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kuusankoski
Kuusankoski is a neighbourhood of city of Kouvola, former industrial town and municipality of Finland, located in the region of Kymenlaakso in the province of Southern Finland. The population of Kuusankoski was 20,392 (2003) and the total area was 129.5 km² of which 114 km² was land and 14.56 km² water. It is located some northeast of the Finnish capital Helsinki. Kuusankoski is primarily known for paper manufacturing and three large factory complexes. It is sometimes nicknamed the "Paper capital of Finland". History Kuusankoski (as a municipality, not the settlement), was founded in 1921 from the parts of neighbouring Iitti and Valkeala. It gained the status of ''kauppala'' (literally ''"a place of commerce"'') in 1957 and became a town in 1973. The history of Kuusankoski during the last one and a half centuries has been closely linked to the establishment of the paper factories and their development. The establishment of the factories dates back to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annals Of Mathematics
The ''Annals of Mathematics'' is a mathematical journal published every two months by Princeton University and the Institute for Advanced Study. History The journal was established as ''The Analyst'' in 1874 and with Joel E. Hendricks as the founding editor-in-chief. It was "intended to afford a medium for the presentation and analysis of any and all questions of interest or importance in pure and applied Mathematics, embracing especially all new and interesting discoveries in theoretical and practical astronomy, mechanical philosophy, and engineering". It was published in Des Moines, Iowa, and was the earliest American mathematics journal to be published continuously for more than a year or two. This incarnation of the journal ceased publication after its tenth year, in 1883, giving as an explanation Hendricks' declining health, but Hendricks made arrangements to have it taken over by new management, and it was continued from March 1884 as the ''Annals of Mathematics''.

Academic Staff Of The University Of Helsinki
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Helsinki Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

Academy Of Finland
The Academy of Finland ( fi, Suomen Akatemia, sv, Finlands Akademi) is a governmental funding body for scientific research in Finland. It is based in Helsinki. Yearly, the Academy administers over 260 million euros to Finnish research activities. Over 5000 researchers are working on projects supported by the academy. The Academy functions as a funding body only and is not a school. However, personnel funded by the Academy can use the title referring to it, e.g. professors will be called ''akatemiaprofessori''. Academy Professor funding has a term of 5 years. The Academy of Finland should not be confused with the Finnish arts and science school learned societies, The Finnish Academy of Science and Letters (''Suomalainen tiedeakatemia'') and The Finnish Society of Science and Letters (''Finska Vetenskaps-Societeten'') which are the two Finnish national honorary academies, for Finnish and Swedish-speaking scientists and scholars, respectively. For engineers, the two language-based h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Congress Of Mathematicians
The International Congress of Mathematicians (ICM) is the largest conference for the topic of mathematics. It meets once every four years, hosted by the International Mathematical Union (IMU). The Fields Medals, the Nevanlinna Prize (to be renamed as the IMU Abacus Medal), the Carl Friedrich Gauss Prize, Gauss Prize, and the Chern Medal are awarded during the congress's opening ceremony. Each congress is memorialized by a printed set of Proceedings recording academic papers based on invited talks intended to be relevant to current topics of general interest. Being List of International Congresses of Mathematicians Plenary and Invited Speakers, invited to talk at the ICM has been called "the equivalent ... of an induction to a hall of fame".

Institute For Advanced Study
The Institute for Advanced Study (IAS), located in Princeton, New Jersey, in the United States, is an independent center for theoretical research and intellectual inquiry. It has served as the academic home of internationally preeminent scholars, including J. Robert Oppenheimer, Albert Einstein, Hermann Weyl, John von Neumann, and Kurt Gödel, many of whom had emigrated from Europe to the United States. It was founded in 1930 by American educator Abraham Flexner, together with philanthropists Louis Bamberger and Caroline Bamberger Fuld. Despite collaborative ties and neighboring geographic location, the institute, being independent, has "no formal links" with Princeton University. The institute does not charge tuition or fees. Flexner's guiding principle in founding the institute was the pursuit of knowledge for its own sake.Jogalekar. The faculty have no classes to teach.

Analytic Capacity
In the mathematical discipline of complex analysis, the analytic capacity of a compact subset ''K'' of the complex plane is a number that denotes "how big" a bounded analytic function on C \ ''K'' can become. Roughly speaking, ''γ''(''K'') measures the size of the unit ball of the space of bounded analytic functions outside ''K''. It was first introduced by Lars Ahlfors in the 1940s while studying the removability of singularities of bounded analytic functions. Definition Let ''K'' ⊂ C be compact. Then its analytic capacity is defined to be :\gamma(K) = \sup \ Here, \mathcal^\infty (U) denotes the set of bounded analytic functions ''U'' → C, whenever ''U'' is an open subset of the complex plane. Further, : f'(\infty):= \lim_z\left(f(z)-f(\infty)\right) : f(\infty):= \lim_f(z) Note that f'(\infty) = g'(0), where g(z) = f(1/z). However, usually f'(\infty)\neq \lim_ f'(z). If ''A'' ⊂ C is an arbitrary set, then we define :\gamma(A) = \sup \. Removable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
