**Abstract**

In this work we investigate the thermodynamical properties and modified dynamics of black hole solutions in the semiclassical regime of affine coherent state quantization. Using the weak correspondence principle we build a semiclassical effective action that we use to study thermodynamics in the canonical ensemble and to compare classical analytical solutions with the corresponding semiclassical ones. We determine a strong compatibility of these affine black holes with the thermodynamical properties of the classical counterparts, with only minor restrictions on the free parameters of the models. Furthermore we obtain that black hole singularities are removed by quantum effects, resulting also in a modified extension of the horizon, in agreement with the sign of entropy corrections.

AdS/CFT correspondence in mathematical rigour as a tool to understand boundary condition of gravity.

**Research Interests:** I’m a theoretical (mathematical) physicist working on noncommutative space-times in approach to Quantum Gravity. In my research I use Quantum Groups framework and some elements of Noncommutative Geometry in the deformation of relativistic symmetries and spacetime.

Currently I am a Postdoc (Junior Principal Investigator, within the Marie Sklodowska Curie COFUND Fellowship –“2020 Researchers : Train 2 Move”(T2M)) at the Dipartimento di Matematica “Giuseppe Peano” (Università degli Studi di Torino) in Italy.

Before that I was Postdoc at Mathematics Division of Science Institute University of Iceland where I moved after finishing my PhD studies at the Institute of Theoretical Physics at University of Wroclaw (Poland).
