SUMMARY:Spontaneous Partial Supersymmetry Breaking - Smyth\, P (EPFL - Eco
 les Polytechniques Fdrales de Lausanne)

DESCRIPTION:I will review some recent work on spontaneous partial supersym
 metry breaking in extended supersymmetry. I will first describe the no-go 
 theorems which forbid N=2 to N=1 spontaneous supersymmetry breaking in glo
 bal and local supersymmetry\, before showing how they are circumvented. I 
 will then discuss some new techniques involving the embedding tensor forma
 lism which allow us to study this problem systemically and find the low-en
 ergy effective theory in the N=1 vacuum. This leads to interesting insight
 s into spontaneous partial supersymmetry breaking in supergravity and stri
 ng theory\, as well as new results in quaternionic geometry. \n
