Abstract

Let a be a column of the m × n matrix M and A a set of its columns. We say that A implies a iff M contains no two rows equal in A but different in a. It is easy to see that if ℳM(A) denotes the columns implied by A, than ℳM(A) is a closure operation. We say that M represents this closure operation. s() is the minimum number of the rows of the matrices representing a given closure operation. s(ℳ) is determined for some particular closure operations.

N2 - Let a be a column of the m × n matrix M and A a set of its columns. We say that A implies a iff M contains no two rows equal in A but different in a. It is easy to see that if ℳM(A) denotes the columns implied by A, than ℳM(A) is a closure operation. We say that M represents this closure operation. s() is the minimum number of the rows of the matrices representing a given closure operation. s(ℳ) is determined for some particular closure operations.
