EXPLICIT SOLUTIONS OF THE EXTENDED SKOROKHOD PROBLEMS
IN TIME-DEPENDENT BOUNDED REGIONS WITH ORTHOGONAL
REFLECTION FIELDS
Abstract: We consider the extended Skorokhod problem for -valued cądląg functions with
the constraining set that changes in time and the reflection field naturally defined by the
standard orthonormal basis. We find an explicit formula for the solution of such an extended
Skorokhod problem in the case where the evolving constraining set is a region sandwiched
between two graphs. We obtain the best Lipschitz constant for the extended Skorokhod map
of this type.
