Primary decomposition of commutative monoid congruences is insensitive to
certain features of primary decomposition in commutative rings. These features
are captured by the more refined theory of mesoprimary decomposition of
congruences, introduced here complete with witnesses and associated prime
objects. The combinatorial theory of mesoprimary decomposition lifts to
arbitrary binomial ideals in monoid algebras. The resulting binomial
mesoprimary decomposition is a new type of intersection decomposition for
binomial ideals that enjoys computational efficiency and independence from
ground field hypotheses. Binomial primary decompositions are easily recovered
from mesoprimary decomposition.
