The international conference "Differential Equations and Topology" devoted to the 100th Anniversary of the birthday of Lev Semenovich Pontryagin was held in Lomonosov Moscow State University, June 17-22, 2008.
Head of the ASR Department RAS Corresponding Member Dmitry P. Kostomarov had a talk "Problems for Ultrahyperbolic Equations in Half-Space" [
Ultrahyperbolic equations are set aside by mathematicians since they are usually not met in applications.
At the same time such equations are very interesting from mathematical point of view, because their solutions possess both hyperbolic and elliptic properties.
In his talk Prof. Kostomarov considered problems in half-space
