The main thrust of present note is a volume formula for hyperbolic surface bundle with the fundamental group G. The novelty consists in a purely algebraic approach to the above problem. Initially, we concentrate on the Baum-Connes morphism μ : K•(BG)→ K•(C ∗ redG) for our class of manifolds, and then classify μ in terms of the ideals in the ring of integers of a quadratic number field K. Next, ...

This paper focuses on how, like Toto from the Wizard of Oz (Baum, 1900) , animal companions can alter course reflective practice by encouraging diffractive shifts in thinking, different connections with world, and a (re)connection with, or re-framing personal professional values ethics.

A doctor has a duty to give his patient what he believes to be the best treatment. An ethical prerequisite of recommending her to enter a randomised clinical trial (RCT), in which his patient will be randomly allotted to one of two or more treatments, is, as Michael Baum in his chapter stresses, that he is ignorant about their relative efficacy and, hence, justifiably indifferent as to which sh...

We indicate which symmetrizable locally compact affine or hyperbolic Kac-Moody groups satisfy Kazhdan’s Property (T), and those that satisfy its strong negation, the Haagerup property. This reveals a new class of hyperbolic Kac-Moody groups satisfying the Haagerup property, namely symmetrizable locally compact Kac-Moody groups of rank 2 or of rank 3 noncompact hyperbolic type. These groups thus...
