A lot of economic problems can formulated as constrained optimizations
and equilibration of their solutions. Various mathematical theories have
been supplying economists with indispensable machineries for these
problems arising in economic theory. Conversely, mathematicians have
been stimulated by various mathematical difficulties raised by economic
theories. The series is designed to bring together those mathematicians
who were seriously interested in getting new challenging stimuli from
economic theories with those economists who are seeking for effective
mathematical tools for their researchers.
