Abstract:
The issues related to the relaxation of a game problem of approach
on a finite time interval are considered. In the original problem, it is assumed
that the following sets are given: a target set closed in the position space and
a set that determines state constraints and whose sections corresponding to fixed
times are closed in the state space. The game termination conditions are relaxed
by replacing these sets with their neighborhoods defined in different topologies
of the position space; the “sizes” of the neighborhoods are related by a
proportionality coefficient in the form of a priority parameter. For each value
of this parameter and a fixed position, we find the value of the relaxed problem,
which coincides with the minimax in the class of quasistrategies for a special
quality functional. It is established that the resulting position function
depends on the parameter continuously as a mapping of the positive semiaxis to
the Tikhonov power of the real line with the position space as the index set.
Regions of uniform continuity are specified for the corresponding calculation
functions (for a fixed position).
