We introduce spectral weights ρ(L) of positive, self-adjoint operators L having dis-crete spectrum away from zero. We provide criteria for measurability and…
It will be a relaxed style expository lecture where ideas will be emphasized rather than technicalities. Zoom Link <https://us02web.zoom.us/j/84346778532?pwd=Wm5yd1E2KzUzNHNmR2RHZ0JxdEFWUT09>Meeting…
Finite-dimensional approximations of noncommutative quantum field theories are matrix models. They often show rich mathematical structures: many of them…
Kasparov’s KK-theory which is based on so called Kasparov-modules can be described much more algebraically using universal extensions and classifying maps…
