On some Sobolev and Pólya-Szegö type inequalities with weights and applications
Trung Hieu Giang, Nguyen Minh Tri, Dang Anh Tuan
We are motivated by studying a boundary-value problem for a class of semilinear degenerate elliptic equations \begin{align}\tag{P}\label{P} \begin{cases} - Δ_x u - |x|^{2α} \dfrac{…

Calderón's problem for some classes of conductivities in circularly symmetric domains
Mai Thi Kim Dung, Dang Anh Tuan
In this note, we study Calderón's problem for certain classes of conductivities in domains with circular symmetry in two and three dimensions. Explicit formulas are obtained for th…
