This past summer, on August 19, 2013, Professor Grace Wales Shugar passed away in Warsaw. Although Canadian (born on May 10, 1918 in Montreal), she spent almost her entire research career in Poland, where she lived from 1952. She was founder and leader of the Warsaw School of Developmental Psycholinguistics, and lectured at many universities in different countries. She was invited to deliver a ...

‎‎‎Recently Samet et al. introduced the notion of $alpha$-$psi$-contractive type mappings and established some fixed point theorems in complete metric spaces. In this paper, we introduce $alpha$-$(psi,varphi)$-contractive mappings and stablish coincidence and common fixed point theorems for two mapping in complete metric spaces. We present some examples to illustrate our results. As application...

We present an interprocedural generalization of the well-known (intraprocedural) Coincidence Theorem of Kam and Ullman, which provides a suucient condition for the equivalence of the meet over all paths (MOP) solution and the maximal xed point (MFP) solution to a data ow analysis problem. This generalization covers arbitrary imperative programs with recursive procedures, global and local variab...

In 1937, Von Neumann [1] established the famous coincidence theorem. Since then, the coincidence theorem was generalized in many directions. Browder [2] first proved some basic coincidence theorems for a pair of set-valued mappings in compact setting of topological vector spaces and gave some applications to minimax inequalities and variational inequalities. Recently, Ding [3] established some ...

Abstract_ _ We prove a common coincidence point theorem for a non-fuzzy mapping and a pair of fuzzy mappings under a ' contraction condition on a metric space in the context of Hausdor¤ metric on the family of fuzzy sets. Further, we establish a common coincidence point theorem on a metric space with the d1 metric on fuzzy sets, which extends a number of recent results. As applications, we obta...
