Abstract

An abstract (vk,br)(v_k,b_r)-configuration is a pair of finite sets of cardinalities vv and bb with a relation on the product of the sets such that each element of the first set is related to the same number kk of elements from the second set and each element of the second set is related to the same number rr of elements in the first set. An example of an abstract configuration is a finite geometry. In this paper we discuss some examples of abstract configurations and, in particular finite geometries, which one encounters in algebraic geometry.
