Abstract Condorcet-compatible election methods are examined and compared. The Ranked Pairs method proves significantly better than Beatpath; that both clone-free, have other desirable properties, makes them much any alternative.

In this paper, we define the concept of compatible and weakly compatible mappings in b-metric spaces and inspired by the Ciric and et. al method, we produce appropriate conditions for given the unique common fixed point for a family of the even number of self-maps with together another two self-maps in a complete b-metric spaces. Also, we generalize this common fixed point theorem for a seq...

in this paper we prove a unique common coupled fixed point theorem for two pairs of $w$-compatible mappings in $s_b$-metric spaces satisfying a contrctive type condition. we furnish an example to support our main theorem. we also give a corollary for junck type maps.

We read with great interest the article Gentry et al. (1) which explores the impact of expanding kidney paired donation (KPD) through participation by compatible pairs. In their abstract they argue that this is a new paradigm of KPD and in their conclusion they indicate that the inclusion of recipients with compatible donors will greatly increase the number of incompatible pairs matched through...
