Adjoint grid parabolic quazilinear boundary-value problems [PDF]
Компьютерные исследования и моделирование, 2012 In the paper we construct the adjoint problem for the explicit and implicit parabolic quazi-linear grid boundary-value problems with one spatial variable; the coefficients of the problems depend on the solution at the same time and earlier times ...

Predictor-corrector domain decomposition algorithm for parabolic problems on graphs
Mathematical Modelling and Analysis, 2012 In this paper, we present a predictor-corrector type algorithm for solution of linear parabolic problems on graph structure. The graph decomposition is done by dividing some edges and therefore we get a set of problems on sub-graphs, which can be solved ...

The generalized Conley index and multiple solutions of semilinear elliptic problems
Abstract and Applied Analysis, 1996 We establish some framework so that the generalized Conley index can be easily used to study the multiple solution problem of semilinear elliptic boundary value problems. Both the parabolic flow and the gradient flow are used.

The domain of parabolicity for the Muskat problem [PDF]
Indiana University Mathematics Journal, 2018 We address the well-posedness of the Muskat problem in a periodic geometry and in a setting which allows us to consider general initial and boundary data, gravity effects, as well as surface tension effects. In the absence of surface tension we prove that the Rayleigh-Taylor condition identifies a domain of parabolicity for the Muskat problem.

Anisotropic total variation flow of non-divergence type on a higher dimensional torus [PDF]
, 2013 We extend the theory of viscosity solutions to a class of very singular nonlinear parabolic problems of non-divergence form in a periodic domain of an arbitrary dimension with diffusion given by an anisotropic total variation energy. We give a proof of a

Accounting for Azimuthal Coupling in Long-Range Ocean Acoustics Calculations
IEEE Access, 2023 The parabolic equation method is an accurate and efficient approach for solving nonseparable problems in ocean acoustics in which there are horizontal variations in the environmental parameters.

Finite element exterior calculus for parabolic problems [PDF]
, 2012 In this paper, we consider the extension of the finite element exterior calculus from elliptic problems, in which the Hodge Laplacian is an appropriate model problem, to parabolic problems, for which we take the Hodge heat equation as our model problem ...

Other approaches for generalized Bernoulli–Euler polynomials and beyond [PDF]
Rendiconti di Matematica e delle Sue Applicazioni, 2023 . This paper is concerned with the study of the non-coercive p(x)-parabolic problems. We prove the existence of entropy solutions for this parabolic equation, and we will conclude some regularity results.
