Bourgain-Brezis-Mironescu-Maz'ya-Shaposhnikova limit formulae for fractional Sobolev spaces via interpolation and extrapolation

Oscar Domínguez, Mario Milman

The real interpolation spaces between $L^{p} (R^{n})$ and $H ˙^{t, p} (R^{n})$ (resp. $H^{t, p} (R^{n})$ ), $t > 0,$ are characterized in terms of fra…

New estimates for the maximal functions and applications

Oscar Domínguez, Sergey Tikhonov

In this paper we study sharp pointwise inequalities for maximal operators. In particular, we strengthen DeVore's inequality for the moduli of smoothness and a logarithmic variant o…
