**U. Biccari** Boundary controllability for a one-dimensional heat equation with a singular inverse-square potential, Mathematical Control and related fields, DOI: 10.3934/mcrf.2019011

**Abstract:** We analyse controllability properties for the one-dimensional heat equation with singular inverse-square potential $u_t-u_{xx}-\frac{\mu}{x^2}u=0\,\,\,(x,t)\in(0,1)\times(0,T)$. For any $\mu <1/4$, we prove that the equation is null controllable through a boundary control $f\in H^1(0,T)$ acting at the singularity point $x=0$. This result is obtained employing the moment method by Fattorini and Russell.
