On the functional equations involving nonlinear generalized 𝑃-compact operators [PDF]
Transactions of the American Mathematical Society, 1969 Introduction. In his recent papers [23], [24], [25] Petryshyn has introduced and studied a class of projectionally compact (P-compact) nonlinear mappings of a real Banach space with property (-)K into itself. The main result of this study was an elementary and essentially a constructive proof of two fixed point theorems for bounded [23], [24] and ...

Liouville-Type Theorem for Nonlinear Elliptic Equations Involving Generalized Greiner Operator
Mathematics, 2022 In this paper, we study the Liouville-type behaviors of the generalized Greiner operators with nonlinear boundary value conditions. We use the technique based upon the method of moving planes.

Parabolic Minkowski convolutions of viscosity solutions to fully nonlinear equations [PDF]
, 2019 This paper is concerned with the Minkowski convolution of viscosity solutions of fully nonlinear parabolic equations. We adopt this convolution to compare viscosity solutions of initial-boundary value problems in different domains.

Liouville properties and critical value of fully nonlinear elliptic operators [PDF]
, 2016 We prove some Liouville properties for sub- and supersolutions of fully nonlinear degenerate elliptic equations in the whole space. Our assumptions allow the coefficients of the first order terms to be large at infinity, provided they have an appropriate
