## Abstract We introduce generalizations of Bessel potentials by considering operators of the form __Ο__[(__I__ β Ξ)^βΒ½^] where the functions __Ο__ extend the classical power case. The kernel of such an operator is subordinate to a growth function __Ξ·__. We explore conditions on __Ξ·__ in such a way

β¦ Synopsis
It is shown that, for certain choices of the defining indices, the generalized LIPSCHITZ spaces on VILEWKIJ groups are incIudec1 in certain FIGA-TALAXAYCA spaces A,, and t h a t the FOURIER series of functions in the letter spaces converge uniformly. This result includes an extension of the classical DIN test, and endpoint versions of BERNSTEIN'S theorem on absolute convergence of FOURIER series.

## Abstract Let __G__ be a locally compact Vilenkin group. We consider the atomic and molecular decomposition of the weighted TriebelβLizorkin spaces on __G.__ As an application of it we prove boundedness results for certain pseudodifferential operators on such spaces.
## Abstract Let __G__ be a locally compact Vilenkin group. Using Herz spaces, we give sufficient conditions for a distribution on __G__ to be a convolution operator on certain Lorentz spaces. Our results generalize HΓΆrmander's multiplier theorem on __G__. (Β© 2008 WILEYβVCH Verlag GmbH & Co. KGaA, W
