Transactions of the American Mathematical Society, Vol. 349, No. 3 (Mar., 1997), pp. 903-934 (32 pages) For every finitely generated, congruence modular variety V of finite type we find a finite ...

Let S be a regular semigroup and let ρ be a congruence relation on S. The kernel of ρ, in notation $\ker \rho$, is the union of the idempotent ρ-classes. The trace of ρ, in notation tr ρ, is the ...

Partition functions, which enumerate the distinct ways a positive integer may be expressed as a sum of positive integers, have long captivated mathematicians due to their deep connections with number ...
