The Method of Lines and the Approximation of Zeros of m-Accretive Operators in General Banach Spaces

open access: yes, 1994
It is shown that a zero of an m-accretive operator T: D(T) ⊂ X → 2X, in a general Banach space X, can be approximated via methods of lines for associated evolution equations.

The Synergy Between Deterministic and Neutral Processes Drives Turnover‐Dominated Beta Diversity of Non‐Volant Small Mammals in the Western Tianshan Mountains, China

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
Through a survey of small mammals in the western Tianshan Mountains, we discovered that the synergy between deterministic and neutral processes drives the turnover‐dominated beta diversity of small mammals. ABSTRACT Exploring multifaceted beta diversity, including its turnover and nestedness components, is crucial for elucidating the drivers of ...

A new system of nonlinear variational inclusions with (Ai , ni)-accretive operators in Banach spaces

open access: yes, 2012
In this paper, we introduce and study a new system of nonlinear variational inclusions with (A, n)-accretive operators in Banach spaces. Using the resolvent operator technique associated with (A, n)-accretive operator, we prove the existence and ...

On the closedness of operator pencils

open access: yes, 2000
Consider an operator pencil A0+λ1A1+···+λnAn in which, for example (other cases are also considered), A0 is a maximal accretive operator, A1, ..., An are closed accretive operators, and dom A0 ⊂ dom Aj, j = ¯1,n¯.

Convergence Theorems for Accretive Operators in Banach Spaces

open access: yes, 2011
In this paper, a new iterative scheme for finding a common element of the set of fixed points of a nonexpansive mapping and the set of the variational inequality for an inverse-strongly accretive operator in a 2-uniformly smooth Banach space was ...

Strictly operator-stable distributions

open access: yes
Strictly operator-stable distributions are defined and discussed. Characterization of strictly stable distributions with exponent 1 is generalized to strictly ([alpha], Q)-stable distributions with [alpha] being an eigenvalue of Q.infinite divisibility ...
