Ergodic Theorems for Nonlinear Contraction Semigroups in a Hilbert Space

摘要

Two ergodic theorems are presented for means of nonlinear contraction semigroups in a Hilbert space. These means are generated by a class of averaging kernels which includes the usual Abel and Cesaro-(C, alpha ) kernels. 7 references. (ERA citation 04:055770)
