Geraardsbergen is a city and municipality located in the Denderstreek and in the Flemish Ardennes, the hilly southern part of the Belgian province of East Flanders. The municipality comprises the city of Geraardsbergen proper and the following towns:
Moerbeke is a municipality in the Belgian province of East Flanders. It is sometimes unofficially called Moerbeke-Waas to distinguish between this place and Moerbeke in Geraardsbergen. The municipality only comprises the town of Moerbeke proper. On January 1, 2006, Moerbeke had a total population of 5,844. The total area is 37.80 km² which gives a population density of 155 inhabitants per km².
William of Moerbeke, O.P., was a prolific medieval translator of philosophical, medical, and scientific texts from Greek language into Latin, enabled by the period of Latin rule of the Byzantine Empire. His translations were influential in his day, when few competing translations were available, and are still respected by modern scholars.
Donald Clayton Spencer was an American mathematician, known for work on deformation theory of structures arising in differential geometry, and on several complex variables from the point of view of partial differential equations. He was born in Boulder, Colorado, and educated at the University of Colorado and MIT.
In mathematics, differential Galois theory studies the Galois groups of differential equations.
Pierre-Louis Lions is a French mathematician. He is known for a number of contributions to the fields of partial differential equations and the calculus of variations. He was a recipient of the 1994 Fields Medal and the 1991 Prize of the Philip Morris tobacco and cigarette company.
Jean-François Le Gall is a French mathematician working in areas of probability theory such as Brownian motion, Lévy processes, superprocesses and their connections with partial differential equations, the Brownian snake, random trees, branching processes, stochastic coalescence and random planar maps. He received his Ph.D. in 1982 from Pierre and Marie Curie University under the supervision of Marc Yor. He is currently professor at the University of Paris-Sud in Orsay and is a senior member of the Institut universitaire de France. He was elected to French academy of sciences, December 2013.
Henry P. McKean, Jr. is an American mathematician at New York University. He works in various areas of analysis. He obtained his PhD in 1955 from Princeton University under William Feller.
Michael Grain Crandall is an American mathematician, specializing in differential equations.
Mikhail Il'ich Zelikin is a Russian mathematician, who works on differential equations, optimal control theory, differential games, the theory of fields of extremals for multiple integrals, the geometry of Grassmannians. He proposed an explanation of ball lightning based on the hypothesis of plasma superconductivity.
In mathematics, the Volterra lattice, also known as the discrete KdV equation, the Kac–van Moerbeke lattice, and the Langmuir lattice, is a system of ordinary differential equations with variables indexed by some of the points of a 1-dimensional lattice. It was introduced by Kac and van Moerbeke (1975) and Moser (1975) and is named after Vito Volterra. The Volterra lattice is a special case of the generalized Lotka–Volterra equation describing predator–prey interactions, for a sequence of species with each species preying on the next in the sequence. The Volterra lattice also behaves like a discrete version of the KdV equation. The Volterra lattice is an integrable system, and is related to the Toda lattice. It is also used as a model for Langmuir waves in plasmas.
