Virasoro constraints for quantum cohomology
A pair of laterally movable sliding doors include one door provided with a vertical hollow side frame member within which is housed a reciprocating locking bar adapted to engage a keeper mounted on the car below the door. The locking bar is reciprocated by a bell crank handle and lever arrangement which is pivotally connected to one end of a rockable link or arm supported on the door, the link including an end projecting into the side frame member for pivotal connection to the upper end of the locking bar.

On the existence of equilibria in generalized games
This paper deals with the existence of equilibrium in generalized games (the so-called abstract economies) and Nash equilibrium in games with general assumptions. Preference correspondences, unlike the existing theorems in the literature, need not have open graphs or open lower sections, strategy spaces need not be compact and finite dimensional, the number of agents need not be countable, and preference relations need not be ordered. Thus, our results generalize many of the existence theorems on equilibria in generalized games, including those of Debreu (1952), Shafer and Sonnenschein (1975), Toussaint (1984), Kim and Richter (1986), and Yannelis (1987).
