Abstract:
Infinite hyperplane arrangements whose vertices form a lattice are
studied from the point of view of commutative algebra. The quotient of
such an arrangement modulo the lattice action represents the minimal
free resolution of the associated binomial ideal, which defines a
toric subvariety in a product of projective lines. Connections to
graphic arrangements and to Beilinson's spectral sequence are
explored.
