Numerical Analysis of an Elliptic-Parabolic Partial Differential Equation [PDF]

open access: yesSIAM Journal on Numerical Analysis, 1968
G. Fichera [1] and other authors have investigated partial differential equations of the form [Eq. 1.1] in which the matrix (aij(x)) is required to be semidefinite. Equations of this type occur in the theory of random processes.

Positive Solutions of a Nonlinear Parabolic Partial Differential Equation [PDF]

open access: yesAbstract and Applied Analysis, 2014
We deal with the existence and uniqueness of positive solutions to a class of nonlinear parabolic partial differential equations, by using some fixed point theorems for mixed monotone operators with perturbation.

Quasilinear parabolic stochastic partial differential equations: existence, uniqueness [PDF]

open access: greenStochastic Processes and their Applications, 2015
In this paper, we provide a direct approach to the existence and uniqueness of strong (in the probabilistic sense) and weak (in the PDE sense) solutions to quasilinear stochastic partial differential equations, which are neither monotone nor locally monotone.

„BLACK-SCHOLES MODEL USED TO EVALUATE STOCKS OPTIONS” [PDF]

open access: yesAnnals of the University of Oradea: Economic Science, 2010
Partial differential equation, parabolic Black-Scholes type, is used in evaluating equity options, that paying constant and continue dividends or in evaluate options in which interest rate, volatility and dividend are dependent on time.

Normal forms for parabolic partial differential equations

open access: green, 1993
Summary: The authors begin a study of normal form theorems for parabolic partial differential equations \[ \partial_ t v= \partial_ x^ 2 v+\mu v-v^ 3- \varepsilon R(v), \] where \(R\) is a polynomial whose terms are all of degree 4 or higher. They show that despite the presence of resonances one can construct a partial normal form for perturbations of ...

Quasilinear Parabolic Equations Associated with Semilinear Parabolic Equations

open access: yesMathematics, 2023
We formulate a quasilinear parabolic equation describing the behavior of the global-in-time solution to a semilinear parabolic equation. We study this equation in accordance with the blow-up and quenching patterns of the solution to the original ...

Large deviations for stochastic Kuramoto–Sivashinsky equation with multiplicative noise

open access: yesNonlinear Analysis, 2021
The Kuramoto–Sivashinsky equation is a nonlinear parabolic partial differential equation, which describes the instability and turbulence of waves in chemical reactions and laminar flames. The aim of this work is to prove the large deviation principle for

Postprocessing for Stochastic Parabolic Partial Differential Equations [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2007
We investigate the strong approximation of stochastic parabolic partial differential equations with additive noise. We introduce postprocessing in the context of a standard Galerkin approximation, although other spatial discretizations are possible. In time, we follow [G. J. Lord and J. Rougemont, IMA J. Numer. Anal., 24 (2004), pp. 587-604] and use an
