Comment on "Remark on the renormalization group equation for the Penner model"
Noureddine Chair
We show explicitly that the sum over punctures for the three times derivative for the Penner free energy , given by D.A. Johnston, Phys.Rev.D 51 (1995) is not correct. A…
Perturbative Chern-Simons Theory From The Penner Model
Noureddine Chair
We show explicitly that the perturbative SU(N) Chern-Simons theory arises naturally from two Penner models, with opposite coupling constants. As a result computations in the pertur…
Partition Identities From Partial Supersymmetry
Noureddine Chair
In the quantum theory, using the notion of partial supersymmetry, in which some, but not all, operators have superpartners we derive the Euler theorem in partition theory. The para…
Explicit Computations for the Intersection Numbers on Grassmannians, and on the Space of Holomorphic Maps from CP^1 into G_r(C^n)
Noureddine Chair
We derive some explicit expressions for correlators on Grassmannian G_r(C^n) as well as on the moduli space of holomorphic maps, of a fixed degree d, from sphere into the Grassmann…
