Some $s$ -numbers of an integral operator of Hardy type in Banach function spaces

David Edmunds, Amiran Gogatishvili, Tengiz Kopaliani +1

Let $s_{n} (T)$ denote the $n$ th approximation, isomorphism, Gelfand, Kolmogorov or Bernstein number of the Hardy-type integral operator $T$ given by $$ Tf(x)=v(x)\int_{a}^{x}u(t)f(…

Asymptotic formulae for s-numbers of a Sobolev embedding and a Volterra type operator

David E. Edmunds, Jan Lang

Sharp upper and lower estimates are obtained of the approximation numbers of a Sobolev embedding and an integral operator of Volterra type. These lead to asymptotic formulae for th…
