DESCRIPTION:In the paper "4d wall crossing via 3d field theory"\,\nGaiotto
 \, Moore\, and Neitzke outline a method\nfor associating a hyperkahler man
 ifold to a quiver\nwith potential. The crucial ingredient is the\nKontsevi
 ch-Soibelman wall-crossing formula\nfor Donaldson-Thomas invariants. Altho
 ugh\ntheir construction has not yet been made\nmathematically rigorous\, I
  will try to sketch\nthe general picture\, and show how it works\nin some 
 particular examples.
