intersection
1. of sets. The set that results from combining elements common to two sets S and T, say, usually expressed as ST

∩ is regarded as an operation on sets, the intersection operation, which is commutative and associative. Symbolically ST = {x | xS and xT}

When two sets S and T intersect in the empty set, the sets are disjoint. Since the intersection operation is associative, it can be extended to deal with the intersection of several sets.

2. of two graphs, G1 and G2. The graph that has as vertices those vertices common to G1 and G2 and as edges those edges common to G1 and G2.

Intersection ★½ 1993 (R)

Successful architect Vincent (Gere) is torn between his aloof wife/partner, Sally (Stone), and a sexy journalist mistress, Olivia (Davidovitch). Whom to choose? Since he's a completely selfinvolved boor, you won't care either way. Another retooling of a French film (“Les Choses de la Vie”) as a Hollywood star vehicle that doesn't work. Lousy dialogue doesn't help. Does boast some nice location shots of Vancouver, B.C. 98m/C VHS, DVD . Richard Gere, Sharon Stone, Lolita (David) Davidovich, Martin Landau, David Selby, Jenny (Jennifer) Morrison; D: Mark Rydell; W: Marshall Brickman, David Rayfiel; C: Vilmos Zsigmond; M: James Newton Howard. Golden Raspberries ‘94: Worst Actress (Stone).
