  • Lower bounds of cowidths and widths of multiplier operators 
    Kushpel, Alexander (2022-04)
    The main objective of this article is to present new results on optimal reconstruction of function classes on probability spaces (Ω,A,ν) in the standard Lq spaces. We consider the problem of optimal reconstruction in the ...
  • Optimal recovery and volume estimates 
    Kushperl, Alexander (2023-12)
    We study volumes of sections of convex origin-symmetric bodies in Rn induced by orthonormal systems on probability spaces. The approach is based on volume estimates of John-Löwner ellipsoids and expectations of norms induced ...
