Sampling projections in the uniform norm
CoRR(2024)
摘要
We show that there are sampling projections on arbitrary n-dimensional
subspaces of B(D) with at most 2n samples and norm of order √(n),
where B(D) is the space of complex-valued bounded functions on a set D.
This gives a more explicit form of the Kadets-Snobar theorem for the uniform
norm and improves upon Auerbach's lemma. We discuss consequences for optimal
recovery in L_p.
