H^0.Recall the following(1.1) Definition. The Mobius function JK: L(X)-+Z is inductively definedbywhere 0 stands for the ambient space (the minimal element in L(XJ).By r(s) we denote the length of the longest chain in L(X) below s (s eIn this article we call a non-void finite family of hyperplanes in C"
