Some recent progress on exponential bases
It is well known that an orthonormal basis of L2(0,2π) is provided by the trigonometric system. In this talk, we will focus on disturbances of the trigonometric system that provide asymptotically orthonormal bases. We will use a method initiated by Nikolski-Hruschev and Pavlov and based on the functional model. This is a work in collaboration with Rishika Rupam.
