  • On the optimality of the trigonometric system 
    Jarad, Fahd; Kushpel, Alexander; Taş, Kenan (Academic Press INC Elsevier Science, 2020-02)
    We study a new phenomenon of the behaviour of widths with respect to the optimality of trigonometric system. It is shown that the trigonometric system is optimal in the sense of Kolmogorov widths in the case of "super-high" ...
  • Widths and entropy of sets of smooth functions on compact homogeneous manifolds 
    Kushpel, Alexander; Taş, Kenan; Levesley, Jeremy (2021)
    We develop a general method to calculate entropy and n-widths of sets of smooth functions on an arbitrary compact homogeneous Riemannian manifold M-d. Our method is essentially based on a detailed study of geometric ...
