Differentiability of Lipschitz mappings into metric spaces: area and co-area formulas

Behnam Esmayli, Paweł Goldstein, Piotr Hajłasz

We give a self-contained exposition of metric differentiability for Lipschitz mappings from sets in Euclidean spaces into arbitrary metric spaces, together with the corresponding a…

The Trudinger inequality is true for $M^{1, s}$ spaces

Ryan Alvarado, Ahmed Dughayshim, Piotr Hajłasz

We prove the Trudinger inequality with exponent $\frac{s}{s - 1}$ for $M^{1, s}$ Sobolev spaces on metric measure spaces under the sole measure growth assumption $μ (B (x, r)) \geq b r^{s}$ .…
