Abstract

top
Denote by L 1 ( K G / K ) the algebra of spherical integrable functions on S U ( 1 , 1 ) , with convolution as multiplication. This is a commutative semi-simple algebra, and we use its Gelfand transform to study the ideals in L 1 ( K G / K ) . In particular, we are interested in conditions on an ideal that ensure that it is all of L 1 ( K G / K ) , or that it is L 0 1 ( K G / K ) . Spherical functions on S U ( 1 , 1 ) are naturally represented as radial functions on the unit disk D in the complex plane. Using this representation, these results are applied to characterize harmonic and holomorphic functions on D .
