Bounded solutions of nonlinear parabolic equations

open access: yesElectronic Journal of Differential Equations, 2010
We are concerned with bounded solutions existing for all times for nonlinear parabolic equations with possibly nonlinear boundary conditions. A counterexample shows that, without an additional condition, a (weak) maximum principle does not hold for ...

Some applications and maximum principles for multi-term time-space fractional parabolic Monge-Ampère equation

open access: yesDemonstratio Mathematica
This study first establishes several maximum and minimum principles involving the nonlocal Monge-Ampère operator and the multi-term time-space fractional Caputo-Fabrizio derivative.

An approach to nonlinear viscoelasticity via metric gradient flows [PDF]

open access: yes, 2013
We formulate quasistatic nonlinear finite-strain viscoelasticity of rate type as a gradient system. Our focus is on nonlinear dissipation functionals and distances that are related to metrics on weak diffeomorphisms and that ensure time-dependent frame ...

The stochastic elementary formula method and approximate travelling waves for semi-linear reaction diffusion equations [PDF]

open access: yes
In this thesis we consider approximate travelling wave solutions for stochastic and generalised KPP equations and systems by using the stochastic elementary formula method of Elworthy and Truman.

Lower semicontinuity of attractors for non-autonomous dynamical systems [PDF]

open access: yes, 2009
This paper is concerned with the lower semicontinuity of attractors for semilinear non-autonomous differential equations in Banach spaces. We require the unperturbed attractor to be given as the union of unstable manifolds of time-dependent hyperbolic

Machine learning‐based prediction of elevated N terminal pro brain natriuretic peptide among US general population

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 859-868, April 2025.
Abstract Aims Natriuretic peptide‐based pre‐heart failure screening has been proposed in recent guidelines. However, an effective strategy to identify screening targets from the general population, more than half of which are at risk for heart failure or pre‐heart failure, has not been well established.

On stability of nonlinear difference equations and some of their applications

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
The issues of stability in solving nonlinear difference equations were considered. Based on a generalized difference analog of the well-known Bihari lemma, stability conditions for a trivial solution based on initial data were obtained, and an a priori ...
