On Lattice Path Counting by Major and Descents
n-dimensional lattice paths which do not touch the hyperplanes
and x(n)-x(1)=-1-K are
enumerated by MacMahon's major index and variations of the major
index. A formula involving determinants is obtained. For n=2 we
also present a formula for counting these lattice paths
simultaneously by major and descents.
