PROPERTY (T) AND LEFT G-INVARIANT COARSE EMBEDDABILITY OF TOPOLOGICAL GROUPS
Let Gbe a topological group with a left G-invariant metric dsatisfying We show that if Gadmits a left G-invariant coarse embedding into a Hilbert space, then Gdoes not have Property (T). As an application of our main results, we show that if Gand Hare two non-trivial countable discrete groups, which admit left G-invariant coarse embeddings into a Hilbert space and is their free product, then has not Property (T).
left G-invariant coarse embedding, Property (T), free product.
