Zuckerman versus Marais: a primatological collision

Brian Zuckerman

So what is a species anyway? A primatological perspective

Since Darwin's time, the question "what a species" has provoked fierce disputes and a tremendous number of publications, from short opinion papers to thick volumes. The debates covered fundamental philosophical questions, such as: Do species exist at all independently of a human observer or are they just a construct of the human mind to categorize nature's organismic diversity and serve as a se...

Viscosity of a classical gas: The rare-collision versus the frequent-collision regime.

The shear viscosity η for a dilute classical gas of hard-sphere particles is calculated by solving the Boltzmann kinetic equation in terms of the weakly absorbed plane waves. For the rare-collision regime, the viscosity η as a function of the equilibrium gas parameters-temperature T, particle number density n, particle mass m, and hard-core particle diameter d-is quite different from that of th...

Notes on the Knapp-Zuckerman theory

The point of these notes is to redefine some of their concepts in terms of the L-group. I observe, however, that it is best and indeed essential for further applications that their results be formulated for reductive groups rather than just for simply-connected semi-simple groups. I use the notation of CIRRAG (On the classification of irreducible representations of real algebraic groups) modifi...
