Introduction to supermatrix techniques (2)
Seminar Room 1, Newton Institute
AbstractExploiting hyperbolic symmetry for asymptotic analysis of the negative moments. Example of a zero dimensional hyperbolic nonlinear sigma model (n.s.m). Failure of the naïve Hubbard-Stratonovich transformation (HST). HST on Schäfer-Wegner domain and reduction to the U(1,1) n.s.m.
If it doesn't, something may have gone wrong with our embedded player.
We'll get it fixed as soon as possible.
