Existence of weak solutions for abstract hyperbolic-parabolic equations [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
In this paper we study the Existence and Uniqueness of solutions for the following Cauchy problem:A2u″(t)+A1u′(t)+A(t)u(t)+M(u(t))=f(t),   t∈(0,T)       (1)u(0)=u0;   A2u′(0)=A212u1;                      where A1 and A2 are bounded linear operators in a ...

Shadowing for discrete approximations of abstract parabolic equations

open access: yesDiscrete & Continuous Dynamical Systems - B, 2008
This paper is devoted to the numerical analysis of abstract semilinear parabolic problems $u'(t) = Au(t) + f(u(t)), u(0)=u^0,$ in some general Banach space $E$. We prove a shadowing Theorem that compares solutions of the continuous problem with those of a semidiscrete approximation (time stays continuous) in the neighborhood of a hyperbolic ...

Evolution operators for higher order abstract parabolic equations [PDF]

open access: yesCzechoslovak Mathematical Journal, 1986
The author shows the existence of an evolution operator for a higher order abstract parabolic equation with variable coefficients. The techniques employed are similar to Tanabe's method [\textit{H. Tanabe}, Osaka Math. J. 12, 363-376 (1960; Zbl 0098.313)].

On quasilinear parabolic evolution equations in weighted Lp-spaces II [PDF]

open access: yes, 2013
Our study of abstract quasi-linear parabolic problems in time-weighted L_p-spaces, begun in [17], is extended in this paper to include singular lower order terms, while keeping low initial regularity.
