THE EULER CHARACTERISTIC OF THE FIBER PRODUCT OF MORSE FUNCTIONS ON THE UNITARY GROUP

Yasuhiko Kamiyama

Abstract:

It is well known that corresponding to a choice of real numbers we obtain the canonical Morse function f on We denote by the fiber product of two copies of f. We fix a positive integer p and set for In this case, we denote the Morse function by We determine Our result generalizes the previous result for the case p = 1.

Keywords and phrases:
