Extremal fixed points and Diophantine equations

Journal of High Energy Physics
The coupling constants of fixed points in the ϵ expansion at one loop are known to satisfy a quadratic bound due to Rychkov and Stergiou. We refer to fixed points that saturate this bound as extremal fixed points.

Fixed Points of Generalized Contractive Maps

Fixed Point Theory and Applications, 2009
We prove some results on the existence of fixed points for multivalued generalized w-contractive maps not involving the extended Hausdorff metric. Consequently, several known fixed point results are either generalized or improved.

Common fixed points for lipschitzian semigroup

Electronic Journal of Differential Equations, 2006
Lim and Xu [4] established a fixed point theorem for uniformly Lipschitzian mappings in metric spaces with uniform normal structure. Recently, Huang and Hong [1] extended hyperconvex metric space version of this theorem, by showing a common fixed point ...
