Alfred Frölicher
Alfred Frölicher (often misspelled Fröhlicher) was a Swiss mathematician (8 October 8 1927 – 1 July 2010). He was a full professor at the Université de Fribourg (1962–1965), and then at the Université de Genève (1966–1993). He introduced the Frölicher spectral sequence and the Frölicher–Nijenhuis bracket and Frölicher spaces and Frölicher groups. He received his Ph.D. from ETH Zurich in 1954, with thesis ''Zur Differentialgeometrie der komplexe Strukturen'' written under the direction of Beno Eckmann and Heinz Hopf Heinz Hopf (19 November 1894 – 3 June 1971) was a German mathematician who worked on the fields of dynamical systems, topology and geometry.

Université De Fribourg
The University of Fribourg (; ) is a public university located in Fribourg, Switzerland. The roots of the university can be traced back to 1580, when the notable Jesuit Peter Canisius founded the Collège Saint-Michel in the City of Fribourg. In 1763, an academy of law was founded by the state of Fribourg which formed the nucleus of the present law faculty. The University of Fribourg was finally created in 1889 by an Act of the parliament of the Swiss Canton of Fribourg. The University of Fribourg is Switzerland's only bilingual university and offers full curricula in both French and German, two of Switzerland's national languages. Students number about 10,000; there are about 200 tenured professors and 700 other academic teaching and research personnel. The Misericorde Campus, constructed between 1939 and 1942, was designed by the architects Honegger and Dumas, students of Swiss architect Le Corbusier. There are five faculties: Catholic theology, law, natural sciences, human ...

Université De Genève
The University of Geneva (French: ''Université de Genève'') is a public research university located in Geneva, Switzerland. It was founded in 1559 by French theologian John Calvin as a theological seminary. It remained focused on theology until the 17th century, when it became a center for enlightenment scholarship. Today, it is the third largest university in Switzerland by number of students. In 1873, it dropped its religious affiliations and became officially secular. In 2009, the University of Geneva celebrated the 450th anniversary of its founding. Almost 40% of the students come from over 150 foreign countries. The university holds and actively pursues teaching, research, and community service as its primary objectives. The University of Geneva is a member of the League of European Research Universities, 4EU+ Alliance, Coimbra Group, International Forum of Public Universities, and European University Association. It is also home to numerous research centers and insti ...

Frölicher Spectral Sequence
In mathematics, the Frölicher spectral sequence (often misspelled as Fröhlicher) is a tool in the theory of complex manifolds, for expressing the potential failure of the results of cohomology theory that are valid in general only for Kähler manifolds. It was introduced by . A spectral sequence is set up, the degeneration of which would give the results of Hodge theory In mathematics, Hodge theory, named after W. V. D. Hodge, is a method for studying the cohomology groups of a smooth manifold ''M'' using partial differential equations. The key observation is that, given a Riemannian metric on ''M'', every coho ... and Dolbeault's theorem.

Frölicher–Nijenhuis Bracket
In mathematics, the Frölicher–Nijenhuis bracket is an extension of the Lie bracket of vector fields to vector-valued differential forms on a differentiable manifold. It is useful in the study of connections, notably the Ehresmann connection, as well as in the more general study of projections in the tangent bundle. It was introduced by Alfred Frölicher and Albert Nijenhuis (1956) and is related to the work of Schouten (1940). It is related to but not the same as the Nijenhuis–Richardson bracket and the Schouten–Nijenhuis bracket. Definition Let Ω*(''M'') be the sheaf of exterior algebras of differential forms on a smooth manifold ''M''. This is a graded algebra in which forms are graded by degree: :\Omega^*(M) = \bigoplus_^\infty \Omega^k(M). A graded derivation of degree ℓ is a mapping :D:\Omega^*(M)\to\Omega^(M) which is linear with respect to constants and satisfies :D(\alpha\wedge\beta) = D(\alpha)\wedge\beta + (-1)^\alpha\wedge D(\beta). Thus, in particular, t ...

Frölicher Space
In mathematics, Frölicher spaces extend the notions of calculus and smooth manifolds. They were introduced in 1982 by the mathematician A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematica ... Alfred Frölicher. Definition A Frölicher space consists of a non-empty set ''X'' together with a subset ''C'' of Hom(R, ''X'') called the set of smooth curves, and a subset ''F'' of Hom(''X'', R) called the set of smooth real functions, such that for each real function :''f'' : ''X'' → R in ''F'' and each curve :''c'' : R → ''X'' in ''C'', the following axioms are satisfied: # ''f'' in ''F'' if and only if for each ''γ'' in ''C'', in C∞(R, R) # ''c'' in ''C'' if and only if for each ''φ'' in ''F'', in C∞(R, R) Let ''A'' and ''B'' be two Frölicher spaces.

Doctor Of Philosophy
A Doctor of Philosophy (PhD, DPhil; or ) is a terminal degree that usually denotes the highest level of academic achievement in a given discipline and is awarded following a course of Postgraduate education, graduate study and original research. The name of the degree is most often abbreviated PhD (or, at times, as Ph.D. in North American English, North America), pronounced as three separate letters ( ). The University of Oxford uses the alternative abbreviation "DPhil". PhDs are awarded for programs across the whole breadth of academic fields. Since it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and, in some cases, defend their work before a panel of other experts in the field. In many fields, the completion of a PhD is typically required for employment as a university professor, researcher, or scientist. Definition In the context o ...

Beno Eckmann
Beno Eckmann (31 March 1917 – 25 November 2008) was a Switzerland, Swiss mathematician who made contributions to algebraic topology, homological algebra, group theory, and differential geometry. Life Born to a Jewish family in Bern, Eckmann received his master's degree from ETH Zurich, Eidgenössische Technische Hochschule Zürich (ETH) in 1939. Later, he studied there under Heinz Hopf, obtaining his Ph.D. in 1941. His dissertation, on homotopy theory, was jointly supervised by Heinz Hopf and Ferdinand Gonseth. In 1942 he obtained a lecturer position at the University of Lausanne. He became an extraordinary professor there before, in 1948, taking a full professorship at ETH Zurich, where he remained until his 1984 retirement. He was also President of the Swiss Mathematical Society for 1961–1962, and the founding head of the Mathematics Research Institute at ETH Zurich from 1964 until his retirement.

Heinz Hopf
Heinz Hopf (19 November 1894 – 3 June 1971) was a German mathematician who worked on the fields of dynamical systems, topology and geometry. Early life and education Hopf was born in Gräbschen, German Empire (now , part of Wrocław, Poland), the son of Elizabeth (née Kirchner) and Wilhelm Hopf. His father was born Jewish and converted to Protestantism a year after Heinz was born; his mother was from a Protestant family. Hopf attended Karl Mittelhaus higher boys' school from 1901 to 1904, and then entered the König-Wilhelm- Gymnasium in Breslau. He showed mathematical talent from an early age. In 1913 he entered the Silesian Friedrich Wilhelm University where he attended lectures by Ernst Steinitz, Adolf Kneser, Max Dehn, Erhard Schmidt, and Rudolf Sturm. When World War I broke out in 1914, Hopf eagerly enlisted. He was wounded twice and received the iron cross (first class) in 1918. After the war Hopf continued his mathematical education in Heidelberg (winter 1919/2 ...
