Constraints on the fine-structure constant variation in the finite-time singularities scenarios

Tomasz Denkiewicz
Institute of Physics, University of Szczecin

Resumo
The talk will be devoted to the scenarios of the singular evolution of the Universe in which the singularities arise in the finite time. The talk will cover constraining some of those scenarios with current observational data using standard candles, standard rulers, and density perturbations. Finally some preliminary results for the variation of the fine structure constant within those models will be given.
