An application of the fixed point theorem to the inverse Sturm-Liouville problem

Dmitry Chelkak

We consider Sturm-Liouville operators $- y^{''} + v (x) y$ on $[0, 1]$ with Dirichlet boundary conditions $y (0) = y (1) = 0$ . For any $1 \leq p < \infty$ , we give a short proof of the characterizati…

Universality in the 2D Ising model and conformal invariance of fermionic observables

Dmitry Chelkak, Stanislav Smirnov

It is widely believed that the celebrated 2D Ising model at criticality has a universal and conformally invariant scaling limit, which is used in deriving many of its properties. H…
