We prove the existence of an equilibrium in an economy with a measure space of agents and a separable Banach commodity space whose positive cone admits an interior point. We follow the truncation argument given at the end of Yannelis [Yannelis, N.C., 1987. Equilibria in noncooperative models of competition, J. Econ. Theory 41, 96–111] and the abstract economy approach as in Shafer [Shafer, W., ...

The findings presented in the article by Khan et al. (1) are very similar to findings that I and two colleagues reported more than 25 years ago (2). In that work, we also employed a flame-thermal treatment of Ti plates to prepare TiO2 films at different temperatures. We also demonstrated water splitting, but under sunlight rather than under artificial illumination. Whereas we reported an energy...

We root this tribute to Nicholas Yannelis in Chapter II of his 1983 Rochester Ph.D. dissertation, and paper with Prabhakar: work strengthens the lower semicontinuity assumption Michael’s continuous selection theorem open sections, leads correspondences defined on a paracompact space values Hausdorff linear topological space. move beyond literature provide necessary sufficient condition for uppe...
