DESCRIPTION:It is quite common to find a discrete set of degenerate vacua 
 in supersymmetric theories. Such vacua may be interpolated by domain walls
 . If a domain wall breaks only half of supersymmetry spontaneously\, it is
  BPS saturated. Recently\, it was discovered that BPS saturated domain wal
 l junctions\, which preserve 1/4 of supersymmetry\, also exist in some mod
 els.\nIn this talk\, I will discuss various topics concerning domain wall 
 junctions in the context of simple generalized Wess-Zumino models: the cen
 tral extension of the supersymmetry algebra\, the calculation of the junct
 ion tension\, and the issue of BPS saturation. I will also discuss the equ
 ivalent of the walls and junctions in d=1+1 dimensional models with a comp
 act space dimension\, where they correspond to solitons and instantons.\n\
