" Morse theory for Harmonic forms"

** Abstract: **

In 1969 E. Calabi asked the following question:
"Does there exist Morse theory of harmonic 1-forms?"
In the lecture I will describe a recent theorem (joint work with G. Katz
and J. Levine),
answering the question of E. Calabi.
Most of the lecture will consist in reminding the main principles
of the Morse critical point theory of functions and the Novikov critical
point theory
of closed 1-forms. I will also describe a beautiful Theorem of Calabi,
which gives
a topological characterization of harmonic 1-forms.

Coffee, Cookies at the faculty lounge at 3:30.

You are invited to join the speaker for further discussion after the
talk at Beit Belgia.
