Hamilton–Jacobi equations with monotone nonlinearities on convex cones [PDF]

open access: diamondAnnales de la Faculté des sciences de Toulouse : Mathématiques
We study the Cauchy problem of a Hamilton–Jacobi equation with the spatial variable in a closed convex cone. A monotonicity assumption on the nonlinearity allows us to prescribe no condition on the boundary of the cone. We show the well-posedness of the equation in the viscosity sense and prove several properties of the solution: monotonicity ...

Dynamical systems method for solving nonlinear equations with monotone operators [PDF]

open access: yesMathematics of Computation, 2010
A review of the authors' results is given. Several methods are discussed for solving nonlinear equations F(u) = f, where F is a monotone operator in a Hilbert space, and noisy data are given in place of the exact data. A discrepancy principle for solving the equation is formulated and justified.

Monotone solutions of a class of nonlinear difference equations [PDF]

open access: yesComputers & Mathematics with Applications, 1994
The authors prove some comparison theorems for the existence of a positive nondecreasing solution of the nonlinear difference equation (1) \(\Delta (p_{k - 1} (\Delta x_{k - 1})^ \sigma) + q_ k x^ \sigma_ k = 0\), \(k = 1,2, \dots\) where \(\sigma > 0\) and \(\{p_ k\}^ \infty_ 0\) is a positive sequence.

Hybrid Newton-type method for a class of semismooth equations [PDF]

open access: yes, 2002
In this paper, we present a hybrid method for the solution of a class of composite semismooth equations encountered frequently in applications. The method is obtained by combining a generalized finite-difference Newton method to an inexpensive direct ...

Positive Decreasing Solutions of Higher-Order Nonlinear Difference Equations

open access: yesAdvances in Difference Equations, 2010
It is shown that the decay rates of the positive, monotone decreasing solutions approaching the zero equilibrium of higher-order nonlinear difference equations are related to the positive characteristic values of the corresponding linearized equation. If
