Intersection Products,.. Although the case of primary interest is when . is a closed imbedding, so . = .∩., there is significant benefit in allowing general morphisms . Let . be the induced morphism. The normal cone C..to . in . is a closed subcone of ..., of pure dimension . We define . to be the result of intersecting

Families of Algebraic Cycles,ally equivalent . 1)-cycles on . determine rationally equivalent k-cycles in each fibre. The basic operations of intersection theory preserve algebraic families. For example, if . is smooth over ., and {α.} and {β.} are algebraic families of cycles, then the intersection products .. · .., also vary
