Program Maximin for Differential Games with Nonsmooth Data presented by Yuri Ledyaev, Ph.D., Department of Mathematics, Western Michigan University

Abstract: We consider a differential game with dynamics described by a differential equation

x(t) = f(x(t), u(t), v(t)), x(0) = x0

where x(t) in Rn is a state vector, u(t) in U and v(t) in V are controls of players. The first player aims at minimizing the value of the cost functional

l(x(T))

and the second player tries to maximize it. The characteristic feature of the differential game is that players use feedback controls u(t) = k(t, x(t)), v(t) = m(t, x(t)). In this talk we discuss recent results on conditions which imply the representation of the value function as more simpler program maximin function, namely

c(t0, x0) = sup   inf   l(x(T; t0, x0, u(.), v(.)))

                 v(.)    u(.)

Organizational Meeting presented by Yuri Ledyaev, Ph.D., Department of Mathematics, Western Michigan University

Abstract: This is a brief organizational meeting to discuss a program for Analysis Seminar (this is also Math 6970-Seminar in Applied Mathematics) for the Fall 2019 semester. Everyone who is interested in analysis, applied mathematics and their application (in particular, in optimization, control theory, differential equations, mathematical finance, mathematical biology, etc.) is invited.
