Convergence conditions for Secant-type methods
Ioannis K. Argyros, Said Hilout (2010)
Czechoslovak Mathematical Journal
Similarity:
We provide new sufficient convergence conditions for the convergence of the secant-type methods to a locally unique solution of a nonlinear equation in a Banach space. Our new idea uses recurrent functions, and Lipschitz-type and center-Lipschitz-type instead of just Lipschitz-type conditions on the divided difference of the operator involved. It turns out that this way our error bounds are more precise than earlier ones and under our convergence hypotheses we can cover cases where earlier...

Dual renormings of Banach spaces

Similarity:
We prove that a Banach space admitting an equivalent WUR norm is an Asplund space. Some related dual renormings are also presented.
Embedding of function spaces of variable order of differentiation in function spaces of variable order of integration
Hans-Gerd Leopold (1999)
Czechoslovak Mathematical Journal
Similarity:
The paper deals with embeddings of function spaces of variable order of differentiation in function spaces of variable order of integration. Here the function spaces of variable order of differentiation are defined by means of pseudodifferential operators.
