报告摘要：In this talk, we introduce the logarithmic fractional Sobolev space via the generalized translation operator on the Dunkl setting and establish several functional-geometric properties of its associated capacity. Furthermore, the continuous embedding of this space into \(L^p(\mu)\) in terms of either the logarithmic fractional Sobolev capacity or a variational functional of a nonnegative Radon measure \(\mu\) is characterized. This work is joint with M. Shi, X. Liu and N. Zhao.
