| Research Abstract |
The study explored the optimization problem to maximize the utility function for the state described by the stochastic differential equations and the problem of nonlinear variational inequalities on mathematical economics. The research results can be summarized as follows:
(1) Publication of a book
This book provides the mathematical foundation for broader applications to mathematical economics.
(2) Development of the penalty method
The penalty equations are developed to solve nonlinear variational inequalities with gradient constraint.
