 Approximate Fixed Point Sequences of Nonlinear Semigroup in Metric Spaces In this paper, we investigate the common approximate fixed point sequences of nonexpansive semigroups of nonlinear mappings \$\{T_t\}_{t \geq 0}\$, i.e., a family such that \$T_0(x)=x\$, \$T_{s+t}=T_s(T_t(x))\$, where the domain is a metric space \$(M,d)\$. In particular we prove that under suitable conditions, the common approximate fixed point sequences set is the same as the common approximate fixed point sequences set of two mappings from the family. Then we use the Ishikawa iteration to construct a common approximate fixed point sequence of nonexpansive semigroups of nonlinear mappings.

 Versions of Schwarz's Lemma for Condenser Capacity and Inner Radius We prove variants of Schwarz's lemma involving monotonicity properties of condenser capacity and inner radius. Also, we examine when a similar monotonicity property holds for the hyperbolic metric. Keywords:condenser capacity, inner radius, hyperbolic metric, Schwarz's lemmaCategories:30C80, 30F45, 31A15

 Lipschitz Type Characterizations for Bergman Spaces We obtain new characterizations for Bergman spaces with standard weights in terms of Lipschitz type conditions in the Euclidean, hyperbolic, and pseudo-hyperbolic metrics. As a consequence, we prove optimal embedding theorems when an analytic function on the unit disk is symmetrically lifted to the bidisk. Keywords:Bergman spaces, hyperbolic metric, Lipschitz conditionCategory:32A36
