Positive definite functions and relative property (T) for subgroups of discrete groups
Published online by Cambridge University Press: 17 April 2009
Abstract
Relative Property (T) for a subgroup H of a group G and its connection with positive definite functions are studied. A relation with the Haagerup approximation property is established. We show that if H is a non-normal subgroup of a group G which has Property (T) and G/H is amenable as a graph then H has finite index in G.
