In this paper, we study the 1-cohomology groups associated with the unitary irreducible representations of locally compact groups of isometries of regular trees.
These notes are the outgrowth of a graduate course on Lie groups I taught at the University of Virginia in 1994 In trying to find a text for the course I discovered that books on Lie groups either presuppose a knowledge of differentiable manifolds o
Lie groups has been an increasing area of focus and rich research since the middle of the 20th century. Procesi's masterful approach to Lie groups through invariants and representations gives the reader a comprehensive treatment of the classical gro
