The series is designed to bring together those mathematicians who are seriously interested in
getting new challenging stimuli from economic theories with those economists who are seeking
effective mathematical tools for their research. A lot of economic problems can be 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.
