Explicit solutions for critical and normal depths in trapezoidal and parabolic open channels

open access: yesAin Shams Engineering Journal, 2013
Normal and critical depths are important parameters in the design of open channels and analysis of gradually varied flow. In trapezoidal and parabolic channels, the governing equations are highly nonlinear in the normal and critical flow depths and thus ...

Optimal control problem for systems governed by nonlinear parabolic equations without initial conditions

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2016
An optimal control problem for systems described by Fourier problem for nonlinear parabolic equations is studied. Control functions occur in the coefficients of the state equations. The existence of the optimal control in the case of final observation is

Parabolic Itô equations with monotone nonlinearities

open access: yesJournal of Functional Analysis, 1978
AbstractIn this paper the equation ut = Lu − F(u) + α(t, ω) is studied, where u(t) ϵ B0 a Banach space. L is an unbounded self-adjoint negative definite operator. F is a monotone nonlinear potential operator. α(t, ω) is a white noise process on B0. With suitable further restrictions on L and F it is proved that the equation has a unique solution. As t →

Cauchy problem for some fractional nonlinear ultra-parabolic equations

open access: yesElectronic Journal of Differential Equations, 2016
Blowing-up solutions to nonlocal nonlinear ultra-parabolic equations is presented. The obtained results will contribute in the development of ultra-parabolic equations and enrich the existing non-extensive literature on fractional nonlinear ultra ...
