Die Bevölkerung in Ost- und Westdeutschlandely. We also obtain multiplicity results for a kind of three point boundary value problem via our extension of Leggett–Williams’ fixed point theorem. Finally, we study the existence and multiplicity of positive solutions for a kind of two point fourth-order problems.口音在加重 发表于 2025-3-25 08:29:56

Fixed Point Theorems for Some Discontinuous Operators,ion or expansion conditions only at one boundary of a conical shell instead of imposing conditions on the two boundaries, as in the original result. The second modification of Krasnosel’skiı̆’s result concerns systems of operator equations and it is due to Precup.agnostic 发表于 2025-3-26 05:06:57

Introduction,in this book and sketching what readers will find in the next chapters. As an illustrative example of some basic ideas to be further generalized later, we study a trivially solvable first order scalar initial value problem depending on a parameter.虚情假意 发表于 2025-3-26 12:51:52

Fixed Point Theorems for Some Discontinuous Operators,alized to different classes of maps and spaces in the literature. In addition, we shall improve on two recent modifications of Krasnosel’skiı̆ fixed point theorem in cones. The first one is due to Cabada, Cid, Infante and collaborators, who obtained fixed point theorems in cones by imposing compress
