Inverse of the Gaussian multiplicative chaos: Lehto welding of Independent Quantum disks

Abstract

In this article, we use the framework of "Random conformal weldings" (by K. Astala, P. Jones, A. Kupiainen, E. Saksman) to prove the existence of Lehto-welding for the inverse for $\gamma <0.1818$ and independent copies for ${\gamma }_2\le {\gamma }_1<0.1818$. In particular, we obtain the existence of some conformaly invariant loop $\Gamma$ that glues two disks with boundary length given by independent copies of GMC on the unit circle. It is still unclear how to show that those loops $\Gamma$ are in fact SLE-loops in a parallel proof to "Integrability of SLE via conformal welding of random surfaces" (by Morris Ang, Nina Holden, and Xin Sun).
