Fractional Parabolic Partial Differential Equations in Anisotropic Spectral Barron Spaces: Regularity and Neural Approximation

Jae-Hwan Choi, Hyojae Lim, Jinsol Seo +2

We study fractional parabolic initial-value problems with lower-order drift and potential terms in anisotropic spectral Barron spaces, defined by weighted space--time Fourier $L^{1}$ …

On the trace theorem to Volterra-type equations with local or non-local derivatives

Jae-Hwan Choi, Jin Bong Lee, Jinsol Seo +1

This paper considers traces at the initial time for solutions of evolution equations with local or non-local derivatives in vector-valued $L_{p}$ spaces with $A_{p}$ weight. To achieve…

Characterizations of weighted Besov and Triebel-Lizorkin spaces with variable smoothness

Jae-Hwan Choi, Jin Bong Lee, Jinsol Seo +1

In this paper, we study different types of weighted Besov and Triebel-Lizorkin spaces with variable smoothness. The function spaces can be defined by means of the Littlewood-Paley…
