DESCRIPTION:Spin-c structures\, which are a kind of complexification of Sp
 in structures\, turn out to be very useful in low-dimensional topology\, e
 specially when studying Heegaard Floer homology of 3-manifolds. However\, 
 the fact that there are several definitions of Spin-c structure\, along wi
 th the fact that the proof of their equivalence is spread out on a number 
 of Russian papers\, can make it hard to understand them. After giving some
  motivations for Spin-c structures\, I’ll try to go through some of the 
 most popular definitions of them and to give an idea of why they are all e
 quivalent.
