On the local integrability and boundedness of solutions to quasilinear parabolic systems [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2004
We introduce a structure condition of parabolic type, which allows for the generalization to quasilinear parabolic systems of the known results of integrability, and boundedness of local solutions to singular and degenerate quasilinear parabolic ...

Existence results for some nonlinear parabolic equations with degenerate coercivity and singular lower-order terms [PDF]

open access: yesMathematica Bohemica, 2023
In this paper, we study the existence results for some parabolic equations with degenerate coercivity, singular lower order term depending on the gradient, and positive initial data in $L^1$.

Carleman inequality for a class of super strong degenerate parabolic operators and applications

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
In this paper, we present a new Carleman estimate for the adjoint equations associated to a class of super strong degenerate parabolic linear problems. Our approach considers a standard geometric imposition on the control domain, which can not be removed

Embedding Operators in Vector-Valued Weighted Besov Spaces and Applications

open access: yesJournal of Function Spaces and Applications, 2012
The embedding theorems in weighted Besov-Lions type spaces 𝐵𝑙,𝑠𝑝,𝑞,𝛾 (Ω;𝐸0,𝐸) in which 𝐸0,𝐸 are two Banach spaces and 𝐸0⊂𝐸 are studied. The most regular class of interpolation space 𝐸𝛼 between 𝐸0 and E is found such that the mixed differential operator ...
