Pointwise bounds of orthogonal expansions on the real line via weighted Hilbert transforms
SB Damelin - Advances in Computational Mathematics, 2007 - Springer
We study pointwise bounds of orthogonal expansions on the real line for a class of
exponential weights of smooth polynomial decay at infinity. As a consequence of our main …
