Galerkin Approximation of the Fractional Hardy Constant

Andreea Dima, Liviu I. Ignat

We establish sharp estimates for the discrete optimal constant of the fractional Hardy Inequality in dimension $N \geq 1$ , with fractional exponent $s\in \left(0,\min\left\{1,\frac{…

Galerkin Approximation of the Fractional Sobolev Constant

Andreea Dima, Liviu I. Ignat

We establish sharp estimates for the discrete optimal constant of the fractional Sobolev inequality in dimension $N \geq 1$ , with fractional exponent $s \in (0, min {1, N /2})$ . The c…
