Expansion-Compression Fixed Point Theorem of Leggett-Williams Type for the Sum of Two Operators and Applications for Some Classes of BVPs

Studia Universitatis Babes-Bolyai Mathematica, 2023
"The purpose of this work is to establish an extension of a Leggett- Williams type expansion-compression fixed point theorem for a sum of two operators. As illustration, our approach is applied to prove the existence of non trivial nonnegative solutions for two-point BVPs and three-point BVPs."

Leggett–Williams Theorems for Coincidences of Multivalued Operators

Nonlinear Analysis: Theory, Methods & Applications, 2008
Let \(X,Y\) be Banach spaces, \(C\) be a cone in \(X\) and let \(\Omega_1,\Omega_2\) be open bounded subsets of \(X\) with \(\overline{\Omega}_1\subset\Omega_2\). For a pair \((L,N)\) consisting of a linear Fredholm operator \(L:\text{dom}\,L\subset X\to Y\) of zero index and an upper semicontinuous (compact convex)-valued multimap \(N:X\multimap Y ...

Leggett–Williams Type Theorems With Applications to Nonlinear Differential and Integral Equations

Nonlinear Analysis: Theory, Methods & Applications, 2015
The authors generalize several results of \textit{R. W. Leggett} and \textit{L. R. Williams} [J. Math. Anal. Appl. 60, 248--254 (1977; Zbl 0352.45005)]. In particular, they consider a class of maps which are more general than the compact ones in an ordered Banach space.

Triple Solutions for a Nonlocal Functional Boundary Value Problem by Leggett–Williams Theorem

Applicable Analysis, 2004
The existence of triple solutions for a second-order nonlocal functional boundary value problem is proved by using a fixed-point theorem on cones in Banach spaces due to Leggett and Williams. The obtained results are new even in the ordinary case for three-point boundary value problems discussed quite recently in [Xiaoming He and Weigao Ge (2002 ...
