Abstract:   Let X be an affine complex hypersurface given by a polynomial equation f= 0 in the affine space Cⁿ. The Alexander invariants of  X describe the topology of the complement  Cⁿ \ X. I will discuss relations between these invariants and the monodromy associated to the function  f: Cⁿ --> C, based on joint work with A. Némethi.

Here are some directions to Northeastern University. Lake Hall and Nightingale Hall can be best accessed from the entrance on the corner of Greenleaf Street and Leon Street. The two halls are connected, with no well-defined boundary in between. In particular, 509 Lake Hall is on the same corridor as 544 Nightingale Hall.

There is free parking available for people coming to the Colloquium at Northeastern's visitor parking (Rennaisance Garage). The entrance is from Columbus Avenue. If coming by car, you should park there and take the parking talon. After the lecture, you may pick up the payment coupon from Maxim Braverman.
