DESCRIPTION:Sergey Mozgovoy\, Trinity College Dublin\nI will discuss an eq
 uivalence between the wall-crossing\nformulas of Kontsevich-Soibelman and 
 of Manschot-Pioline-Sen for the\nBPS invariants. This will lead to a close
  study of abelian quiver\ninvariants. We will see that these invariants sa
 tisfy some new\nwall-crossing formulas. They also have polynomiality\, int
 egrality\, and\npositivity properties similar to the properties of BPS inv
 ariants.\nThis is a joint project with Markus Reineke.
