DESCRIPTION:Jaspreet Singh\, UCLA\n\n\nTitle: Smooth Calabi-Yau varieties w
 ith large index and Betti numbers\n\n\nAbstract: A normal variety X is cal
 led Calabi-Yau if its canonical divisor is Q-linearly equivalent to 0. The
  index of X is the smallest positive integer m so that mK_X~0. We construc
 t smooth\, projective Calabi-Yau varieties in every dimension with doubly 
 exponentially growing index\, which we conjecture to be maximal in every d
 imension. We also construct smooth\, projective Calabi-Yau varieties with 
 extreme topological invariants\; namely\, their Euler characteristics and 
 the sums of their Betti numbers grow doubly exponentially. These are conje
 cturally extremal in every dimension. The varieties we construct are known
  in small dimensions but we believe them to be new in general. This work b
 uilds off of the singular Calabi-Yau varieties found by Esser\, Totaro\, a
 nd Wang.
