Invitation to finite groups
Teo Banica
This is an introduction to the finite groups, with focus on the groups of permutations and reflections, and more generally, on the finite groups of unitary matrices. We first discu…
Basic quantum algebra
Teo Banica
This is an introduction to quantum algebra, from a geometric perspective. The classical spaces , such as the Lie groups, homogeneous spaces, or more general manifolds, are descr…
Measure and integration
Teo Banica
This is an introduction to measure theory, integration and function spaces, with all the needed preliminaries included, and with some applications included as well. We first discus…
Compact Kac algebras and commuting squares
Teodor Banica
We consider commuting squares of finite dimensional von Neumann algebras having the algebra of complex numbers in the lower left corner. Examples include the vertex models, the spi…
