Factorization of Almost Periodic Matrix Functions and its Applications 


Ilya Spitkovsky 






(College of William and Mary, Williamsburg, VA, USA)






Abstract. 
We will give an overview of the current state of the spectral theory of
Toeplitz operators with matrix semi almost periodic symbol. The role of
the factorization problem for purely almost periodic (in Bohr sense)
matrix functions will be explained. Existence of factorization will be
discussed along with algorithms of its actual construction. Applications
include (but are not limited to) convolution type equations on finite
intervals.











Seminars take place in Lisbon, I.S.T. -
