Fixed points for singlevalued operators with respect to tau-distance

In this paper we first recall the concept of tau-distance on a metric space. Then, we prove a fixed point theorem for singlevalued operators in terms of a tau-distance.fixed point, tau-distance, singlevalued ...

Core Many-to-one Matchings by Fixed-point Methods [PDF]

We characterize the core many-to-one matchings as fixed points of a map. Our characterization gives an algorithm for finding core allocations; the algorithm is efficient and simple to implement.

From an Abstract Maximal Element Principle to Optimization Problems, Stational Point Theorems and Common Fixed Point Theorems

, 2011
[[abstract]]In this paper, we first establish an existence theorem related with intersection theorem, maximal element theorem and common fixed point theorem for multivalued maps by applying an abstract maximal element principle proved by Lin and Du. Some

Fixed Point Theorems in Computability Theory

We give a quick survey of the various fixed point theorems in computability theory, partial combinatory algebra, and the theory of numberings, as well as generalizations based on those. We also point out several open problems connected to these.
