We consider an abstract second order non-autonomous evolution equation in a Hilbert space H : u ″ + Au γ ( t ) ′ f = 0, where A is self-adjoint and nonnegative operator on , conservative -valued function with polynomial growth (not necessarily to be monotone), time-dependent damping term. How exactly the decay of energy affected by coefficient exponent associated nonlinear term ? There seems li...

0 ∈ Tx + λCx, where T : D(T )⊂ X → 2X is a strongly quasibounded maximal monotone operator and C : D(C)⊂ X → X∗ satisfies the condition (S+)D(C) with L⊂ D(C). The method of approach is to use a topological degree theory for (S+)L-perturbations of strongly quasibounded maximal monotone operators, recently developed by Kartsatos and Quarcoo. Moreover, applying degree theory, a variant of the Fred...

In this paper we analyze the iteration-complexity of the hybrid proximal extragradient (HPE) method for finding a zero of a maximal monotone operator recently proposed by Solodov and Svaiter. One of the key points of our analysis is the use of a new termination criteria based on the εenlargement of a maximal monotone operator. The advantages of using this termination criterion it that its defin...
