Wavelets associated with Hankel transform and their Weyl transforms
《Science China Mathematics》2004年第3期393-400,共8页PENG Lizhong MA Ruiqin LMAM, School of Mathematical Sciences, Peking University, Beijing 100871, China 
This work was supported by the National Natural Science Foundation of China(Grant No.90104004);973 Project of China(Grant No.G1999075105).
The Hankel transform is an important transform. In this paper, westudy the wavelets associated with the Hankel transform, thendefine the Weyl transform of the wavelets. We give criteria of itsboundedness and compactne...
