Prof. Isabelle Chalendar (Université Gustave Eiffel, Paris) will present her research in Analysis.
In 1887, G. Koenigs gave a full description of the point spectrum of composition operators on Hol(D) associated with a symbol f with a fixed point in D.
We will describe the spectrum of such operators for every symbol and then we will give the spectral properties for the weighted composition operators associated with a symbol with an interior fixed point.
Joint work with Eddy Bernard and Benjamin Célariès.
The talks are held using zoom. Anyone interested in attending (outside the School of Mathematics) should email Ben Sharp at firstname.lastname@example.org to request zoom coordinates
