DESCRIPTION:Speakers: Bisweswar Sen ()\nWe study aspects of black-hole spa
 cetimes in the presence of dark-energy components\, focusing on how the eq
 uation of state and associated curvature diagnostics constrain physically 
 distinct regimes. Starting from the Schwarzschild geometry\, we derive the
  Kretschmann scalar as a coordinate-invariant measure of curvature and use
  it to characterize the behavior near the horizon and at the central singu
 larity. We then discuss how dark-energy motivated modifications can be inc
 orporated and how they affect invariant quantities and horizon structure. 
 Our results provide a compact set of analytic expressions and checks that 
 are useful for comparing different dark-energy/black-hole models.\n\nhttps
