TITLE: Thick points for a Gaussian Free Field in 4 dimensions

ABSTRACT:  This joint work with Rajat Subhra Hazra is concerned with the study of the fractal
dimension of thick points for a 4-dimensional Gaussian Free Field. We adopt the definition
of Gaussian Free Field on R^4 introduced by Chen and Jakobson (2012) viewed as an abstract
Wiener space with underlying Hilbert space H^2(R^4). We can prove that for 0 ≤ a ≤ 4 the
Hausdorff dimension of the set of a-high points is 4 − a, and we show that this set is the support of the 4-dimensional Liouville quantum gravity measure.
