Multivalued Functions in Digital Topology
We study several types of multivalued functions in digital topology
An ordered framework for partial multivalued functors
The category Rel of sets and relations intimately ties the notions of
function, partial multivalued function, and direct image under a function
through the description of Rel as the Kleisli category of the covariant power
set functor on Set. We present a suitable framework to obtain a similar
relationship between the concepts of functor, partial multivalued functor, and
the direct image under a functor.Comment: Accepted for presentation at the Asia-Pacific World Congress on

Universal Nash Equilibrium Strategies for Differential Games
The paper is concerned with a two-player nonzero-sum differential game in the
case when players are informed about the current position. We consider the game
in control with guide strategies first proposed by Krasovskii and Subbotin. The
construction of universal strategies is given both for the case of continuous
and discontinuous value functions. The existence of a discontinuous value
function is established. The continuous value function does not exist in the
general case. In addition, we show the example of smooth value function not
being a solution of the system of Hamilton--Jacobi equation.Comment: 23 page
Multivalued function spaces and Atsuji spaces
[EN] In this paper we present two themes. The first one describes a transparent treatment of some of the recent results in graph topologies on multi-valued functions. The study includes Vietoris topology, Fell topology, Fell uniform topology on compacta and uniform topology on compacta. The second theme concerns when continuity is equivalent to proximal continuity or uniform continuityNaimpally, S. (2003). Multivalued function spaces and Atsuji spaces.
