Exponents of 2-multiarrangements and multiplicity lattices

Takuro Abe, Yasuhide Numata

Published 2007-05-31, updated 2011-04-18Version 2

We introduce a concept of multiplicity lattices of 2-multiarrangements, determine the combinatorics and geometry of that lattice, and give a criterion and method to construct a basis for derivation modules effectively.
