Erhard Heinz
Erhard Heinz (30 April 1924, Bautzen – 29 December 2017, Göttingen) was a German mathematician known for his work on partial differential equations, in particular the Monge–Ampère equation. He worked as professor in Stanford, Munich and from 1966 until his retirement 1992 at the University of Göttingen. Heinz obtained his PhD in 1951 under the supervision of Franz Rellich at the University of Göttingen. His most important scientific work deals with the existence and regularity theory of systems of non-linear partial differential equations, with applications to differential geometry and mathematical physics. He obtained important results in the theory of surfaces with prescribed mean curvature, in particular of minimal surfaces, for the Weyl embedding problem, and for systems of Monge-Ampère type. In 1994 he was awarded the Cantor medal. His doctoral students include Hans Wilhelm Alt, Wolf von Wahl, Willi Jäger, Helmut Werner, Reinhold Böhme, Friedrich Tomi, and Frie ...

Willi Jäger
Willi Jäger (born 15 August 1940 in Kschellowitz, Bohemia) is a German mathematician. He completed his PhD in 1966 the University of Munich under the direction of Erhard Heinz. From 1969 to 1970 Jäger was a visiting scientist at the Courant Institute in New York City. In 1970 he became professor of mathematics at the University of Münster and from 1974 he became professor of applied mathematics at the Heidelberg University. In 1987 Jäger was founding member of the Interdisciplinary Center for Scientific Computing in Heidelberg. He is a board member of the Mathematical Research Institute of Oberwolfach. In addition to problems of scientific computing, including the effective use of computers for the mathematical modeling of complicated, mostly scientific problems, Jäger deals with problems of nonlinear differential equations, calculus of variations, branching processes, and the spectral theory of differential operators, mostly with a view to specific applications suc ...

Hans Wilhelm Alt
Hans Wilhelm Alt (born 1945, Hilden) is a German mathematician, specializing in partial differential equations and their applications. Alt received his ''Abitur'' in 1965 from the prestigious secondary school Helmholtz-Gymnasium Hilden. In 1971 he received his PhD from the Georg-August-Universität Göttingen under Erhard Heinz with thesis ''Verzweigungspunkte von H-Flächen'' (Branching points of H-surfaces.) Alt became a professor at the Institute for Applied Mathematics at the University of Bonn, where he retired as professor emeritus in 2010. In 2011 he was made an honorary professor at the Technical University of Munich. His research deals with, among other topics, free boundary value problems for elliptic partial differential equations and hyperbolic partial differential equations with applications to mechanics and thermodynamics. For example, he has done research on axially symmetric jet flows and propagation of fluids in inhomogeneous porous media. More recently, he ha ...

Minimal Surfaces
In mathematics, a minimal surface is a surface that locally minimizes its area. This is equivalent to having zero mean curvature (see definitions below). The term "minimal surface" is used because these surfaces originally arose as surfaces that minimized total surface area subject to some constraint. Physical models of area-minimizing minimal surfaces can be made by dipping a wire frame into a soap solution, forming a soap film, which is a minimal surface whose boundary is the wire frame. However, the term is used for more general surfaces that may self-intersect or do not have constraints. For a given constraint there may also exist several minimal surfaces with different areas (for example, see minimal surface of revolution): the standard definitions only relate to a local optimum, not a global optimum. Definitions Minimal surfaces can be defined in several equivalent ways in R3. The fact that they are equivalent serves to demonstrate how minimal surface theory lies at the ...

Bautzen
Bautzen () or Budyšin () is a hill-top town in eastern Saxony, Germany, and the administrative centre of the district of Bautzen. It is located on the Spree river. In 2018 the town's population was 39,087. Until 1868, its German name was ''Budissin''. In 1945 the Battle of Bautzen was Hitler’s last victory against the Soviet Union during the Battle of Berlin . Bautzen is often regarded as the unofficial, but historical capital of Upper Lusatia. The town is also the most important cultural centre of the Sorbian minority, which constitutes about 10 percent of Bautzen's population. Asteroid '' 11580 Bautzen'' is named in honour of the city. Names Like other cities and places in Lusatia, Bautzen has several different names across languages. Its German name was also officially changed in 1868. As well as ''Bautzen'' (German) and ''Budyšin'' (Upper Sorbian), the town has had the following names: * German: ''Budissin'' (variants used from c. 11th century onwards; Saxon governme ...

Mathematical Physics
Mathematical physics refers to the development of mathematics, mathematical methods for application to problems in physics. The ''Journal of Mathematical Physics'' defines the field as "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories". An alternative definition would also include those mathematics that are inspired by physics (also known as physical mathematics). Scope There are several distinct branches of mathematical physics, and these roughly correspond to particular historical periods. Classical mechanics The rigorous, abstract and advanced reformulation of Newtonian mechanics adopting the Lagrangian mechanics and the Hamiltonian mechanics even in the presence of constraints. Both formulations are embodied in analytical mechanics and lead to understanding the deep interplay of the notions of symmetry (physics), symmetry and conservation law, con ...

Differential Geometry
Differential geometry is a mathematical discipline that studies the geometry of smooth shapes and smooth spaces, otherwise known as smooth manifolds. It uses the techniques of differential calculus, integral calculus, linear algebra and multilinear algebra. The field has its origins in the study of spherical geometry as far back as antiquity. It also relates to astronomy, the geodesy of the Earth, and later the study of hyperbolic geometry by Lobachevsky. The simplest examples of smooth spaces are the plane and space curves and surfaces in the three-dimensional Euclidean space, and the study of these shapes formed the basis for development of modern differential geometry during the 18th and 19th centuries. Since the late 19th century, differential geometry has grown into a field concerned more generally with geometric structures on differentiable manifolds. A geometric structure is one which defines some notion of size, distance, shape, volume, or other rigidifying structu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
