During the last fifty years complicated mathematical instruments became a vital part within the improvement of recent fiscal concept. Economists proceed to invoke subtle mathematical innovations and concepts for you to comprehend advanced monetary and social difficulties. within the final ten years the speculation of Riesz areas (vector lattices) has been effectively utilized to monetary thought. through now it's understood fairly good that the lattice constitution of Riesz areas may be hired to seize and interpret numerous financial notions. On April 16-20, 1990, a small convention on Riesz areas, confident Opera tors, and their functions to Economics happened on the California Institute of know-how. the aim of the convention was once to carry mathematicians specific ized in Riesz areas and economists really good mostly Equilibrium jointly to interchange rules and increase the interdisciplinary cooperation among math ematicians and economists. This quantity is a suite of papers that signify the talks and discussions of the members on the week-long convention. We take this chance to thank all of the individuals of the convention, specially these whose articles are contained during this quantity. We additionally significantly ap preciate the monetary help supplied through the California Institute of expertise. particularly, we exhibit our sincerest because of David Grether, John Ledyard, and David Wales for his or her aid. eventually, we wish to thank Susan Davis, Victoria Mason, and Marge D'Elia who dealt with the fragile logistics for the graceful operating of the confer ence.
