Ma. Mourou et K. Trimeche, CALDERONS REPRODUCING FORMULA ASSOCIATED WITH THE BESSEL OPERATOR, Journal of mathematical analysis and applications, 219(1), 1998, pp. 97-109
A generalized convolution # on the half-line corresponding to the Bess
el differential operator is introduced. A Calderon reproducing formula
associated with # involving finite Borel measures is studied, leading
to results on the L-P-norm and pointwise approximation for functions
on the half-line. (C) 1998 Academic Press.
