No.6Speaker: Sakdithut Jitpienka, Ph.D. student at IF, Naresuan Univ.) Title: ” Challenges for scaling cosmologies “ Abstract: In this presentation, we review the coincidence problem in Cosmology. we also present away to deal with this problem, i.e., the Universe with the scaling solutions. The generic
form of a scalar-field Lagrangian that possesses scaling solutions in the case where the
coupling Q between dark energy and dark matter is a free function of the field φ is
shown in this presentation. We analyze the existence and stability of all fixed points in
the coupled dark energy model. All possible sequences of the cosmic evolution of these
fixed points are also discussed.
