Maximal $L^{1}$-regularity for parabolic boundary value problems with inhomogeneous data in the half-space

Abstract

End-point maximal L 1 -regularity for the parabolic initial-boundary value problem is considered in the half-space. For the inhomogeneous boundary data of both the Dirichlet and the Neumann type, maximal L 1 -regularity for the initial-boundary value problem of parabolic equation is established in time end-point case upon the Besov space as well as the optimal trace estimates. We derive the almost orthogonal properties between the boundary potentials of the Dirichlet and the Neumann boundary data and the Littlewood-Paley dyadic decomposition of unity.

Partial Fourier Transform Method for Solution Formula of Stokes Equation with Robin Boundary Condition in Half-space

“…Furthermore, Maryani et al (2022) prove the R-boundedness of the solution operator families of Navier-Lame equation problem by using partial Fourier transform. Ogawa & Shimizu (2020) considered the L 1 -regularity class for the initial boundary value problem of parabolic equation in half-space. Other researchers who consider the korteweg model are (Bresch et al, 2019).…”
