Grothendieck-Lidskii trace formula for mixed-norm and variable Lebesgue spaces

Julio Delgado, Michael Ruzhansky, Baoxiang Wang

In this note we present the metric approximation property for weighted mixed-norm $L_w^{(p_1,\dots ,p_n)}$ and variable exponent Lebesgue type spaces. As a consequence, this also i…
