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. 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.
