Title: Affine quantization of FRW universe and some cosiderations about semiclassical analysis
Abstract: In my talk I will introduce phenomenological method appropriate to deal with quantum systems originating from classical systems defined on half-plane phase space. In order to use the mentioned method I will present theory of affine coherent states and integral quantization. By applying affine quantization (affine coherent states integral quantization) to FRW universe we will get one of the well estabilished results of quantum cosmology- initial singularity avoidance. By rough semiclassical analysis we will get some properties of the Big Bounce. I will end my talk by presenting some ideas to improve semiclassical analysis by using coherent states.
