On a Neumann Problem with an Intrinsic Operator
AxiomsThis paper investigates the existence and location of solutions for a Neumann problem driven by a (p,q) Laplacian operator and with a reaction term that depends not only on the solution and its gradient but also incorporates an intrinsic operator, which ...

Uniformly continuous set-valued composition operators in the space of total φ-bidimensional variation in the sense of Riesz [PDF]
Opuscula Mathematica, 2010 In this paper we prove that if a Nemytskij composition operator, generated by a function of three variables in which the third variable is a function one, maps a suitable large subset of the space of functions of bounded total \(\varphi\)-bidimensional ...

Maximal functions and subordination for operator groups. [PDF]
, 2002 Let E be a UMD Banach space and L a positive and self-adjoint operator in L^2 of Laplace type such that the imaginary powers L^{-it} form a C_0 group of exponential growth on L^p(E).

On the Autonomous Nemytskij Operator in Hölder Spaces
Zeitschrift für Analysis und ihre Anwendungen, 1999 The paper is devoted to the autonomous Nemytskij operator (superposition operator) in Hölder spaces H^{k+\alpha}[a,b], (k, \alpha) \in \mathbb Z_+ \times [0, 1]. We study acting, continuity, Lipschitz continuity, and Fréchet differentiability conditions. For

Journal of Function Spaces, Volume 2018, Issue 1, 2018., 2018 We prove the existence of extremal solutions of the following quasilinear elliptic problem -∑i=1N∂/∂xiai(x,u(x),Du(x))+g(x,u(x),Du(x))=0 under Dirichlet boundary condition in Orlicz‐Sobolev spaces W01LM(Ω) and give the enclosure of solutions. The differential part is driven by a Leray‐Lions operator in Orlicz‐Sobolev spaces, while the nonlinear term g ...

Locally Lipschitz Composition Operators in Space of the Functions of Bounded κΦ‐Variation
Journal of Function Spaces, Volume 2014, Issue 1, 2014., 2014 We give a necessary and sufficient condition on a function h:R→R under which the nonlinear composition operator H, associated with the function h, Hu(t) = h(u(t)), acts in the space κΦBV[a, b] and satisfies a local Lipschitz condition.

Application of Spectral Methods to Boundary Value Problems for Differential Equations
International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011 We try to generalize the concept of a spectrum in the nonlinear case starting from its splitting into several subspectra, not necessarily disjoint, following the classical decomposition of the spectrum. To obtain an extension of spectrum with rich properties, we replace the identity map by a nonlinear operator J acting between two Banach spaces X and Y,

A real analyticity result for a nonlinear integral operator [PDF]
, 2013 International audienceWe consider a nonlinear integral operator which involves a Nemytskij type operator and which appears in the applications as a pull-back of layer potential operators. We prove an analyticity result in Schauder spaces by splitting the
