Gerd Grubb
Gerd Grubb (born 1939) is a Danish mathematician known for her research on pseudo-differential operators. She is a professor emerita in the Department of Mathematical Sciences at the University of Copenhagen, where she was the first female professor of mathematics. Education and career Grubb was born on 12 February 1939 in Copenhagen, the daughter of two chemical engineers. She was a student at the Øregård Gymnasium, and then studied various sciences at the University of Copenhagen from 1956 until 1959. After earning a master's degree in mathematics at Aarhus University in 1963, she went to Stanford University for doctoral study in mathematics, completing a Ph.D. in 1966. Her dissertation, ''A Characterization of the Non-Local Boundary Value Problems Associated With an Elliptic Operator'', was supervised by Ralph S. Phillips. She completed a habilitation (Dr. Phil.) in 1975 at the University of Copenhagen, with the habilitation thesis ''Semiboundedness and other properties of no ...

Pseudo-differential Operator
In mathematical analysis a pseudo-differential operator is an extension of the concept of differential operator. Pseudo-differential operators are used extensively in the theory of partial differential equations and quantum field theory, e.g. in mathematical models that include ultrametric pseudo-differential equations in a non-Archimedean space. History The study of pseudo-differential operators began in the mid 1960s with the work of Kohn, Nirenberg, Hörmander, Unterberger and Bokobza. They played an influential role in the second proof of the Atiyah–Singer index theorem via K-theory. Atiyah and Singer thanked Hörmander for assistance with understanding the theory of pseudo-differential operators. Motivation Linear differential operators with constant coefficients Consider a linear differential operator with constant coefficients, : P(D) := \sum_\alpha a_\alpha \, D^\alpha which acts on smooth functions u with compact support in R''n''. This operator can be wri ...

Aarhus University Alumni
Aarhus (, , ; officially spelled Århus from 1948 until 1 January 2011) is the second-largest city in Denmark and the seat of Aarhus municipality, Aarhus Municipality. It is located on the eastern shore of Jutland in the Kattegat sea and approximately northwest of Copenhagen. The largest city in Jutland, Aarhus anchors the Central Denmark Region and the statistical region ' (''LØ'') (lit.: Province East Jutland). The LØ is the second most populous statistical region in Denmark with an estimated population of 903,974 (). Aarhus Municipality defines the greater Aarhus area as itself and eight adjacent municipalities totalling 952,824 inhabitants () which is roughly analogous to the municipal and commercial collaboration Business Region Aarhus. The city proper, with an estimated population of 285,273 inhabitants (), ranks as the List of cities and towns in Denmark, 2nd-largest city in Denmark. Aarhus dates back to at least the late 8th century and is among the oldest cities ...

University Of Copenhagen 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 i ...

Women Mathematicians
A woman is an adult female human. Prior to adulthood, a female human is referred to as a girl (a female child or adolescent). The plural ''women'' is sometimes used in certain phrases such as "women's rights" to denote female humans regardless of age. Typically, women inherit a pair of X chromosomes, one from each parent, and are capable of pregnancy and giving birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, SRY-gene on either one of the respective sex chromosomes. Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. A fully developed woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. Women have significantly less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular than men. Througho ...

Den Store Danske Encyklopædi
''Den Store Danske Encyklopædi'' (''The Great Danish Encyclopedia'') is the most comprehensive contemporary Danish language encyclopedia. The 20 volumes of the encyclopedia were published successively between 1994 and 2001; a one-volume supplement was published in 2002 and two index volumes in 2003. The work comprises 115,000 articles, ranging in size from single-line cross references to the 130-page entry on Denmark. The articles were written by a staff of about 4,000 academic experts led by editor-in-chief Jørn Lund. Articles longer than a few dozen lines are signed by their authors. Many articles are illustrated. The encyclopedia was published by ''Danmarks Nationalleksikon A/S'' (Denmark's National Encyclopedia), a subsidiary of Denmark's publishing house Gyldendal that was set up for the purpose. The project was inspired by the almost contemporary Swedish ''Nationalencyklopedin''; it received financial support from the Augustinus Foundation and was backed by a governmenta ...

Professor Emerita
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Proto ...
