Freiman t-spread principal Borel ideals
Abstract
An equigenerated monomial ideal I is a Freiman ideal if μ(I2)=(I)μ(I)-(I) 2 where (I) is the analytic spread of I and μ(I) is the least number of monomial generators of I. Freiman ideals are special since there exists an exact formula computing the least number of monomial generators of any of their powers. In this paper we give a complete classification of Freiman t-spread principal Borel ideals.
