DESCRIPTION:Taniya Mandal\nAttractor mechanism provides the macroscopic de
 scription of entropy for extremal black holes. As a consequence of this pr
 operty\, the moduli fields of these extremal black holes are fixed at thei
 r horizon and are given by the black hole charges irrespective of their as
 ymptotic values. Hence the entropy of these black holes is solely dependen
 t on the black hole charges. However\, this is the case only when the modu
 li space is connected. If the moduli space contains several disjoint branc
 hes\, black holes possess multiple attractors. The entropy and the attract
 or solution are unique in each branch. In this talk\, I will discuss some 
 examples of multiple attractors with suitable charge configurations in the
  context of four-dimensional\, N=2 supergravity theory coupled to vector m
 ultiplets. The case of axionic black holes for which the attractors underg
 o a phase transition as we change the values of charges across a domain in
  the charge lattice will also be considered. Besides\, I will also discuss
  the effect of Freudenthal duality on the supersymmetric black holes and t
 he full black hole solution for the same
