Field theory amplitudes in a space with SU(2) fuzziness
H. Komaie-Moghaddam, A. H. Fatollahi, M. Khorrami
The structure of transition amplitudes in field theory in a three-dimensional space whose spatial coordinates are noncommutative and satisfy the SU(2) Lie algebra commutation relat…
Loop diagrams in space with SU(2) fuzziness
H. Komaie-Moghaddam, M. Khorrami, A. H. Fatollahi
The structure of loop corrections is examined in a scalar field theory on a three dimensional space whose spatial coordinates are noncommutative and satisfy SU(2) Lie algebra. In p…
A duality theorem for generalized local cohomology
Marc Chardin, Kamran Divaani-Aazar
We prove a duality theorem for graded algebras over a field that implies several known duality results : graded local duality, versions of Serre duality for local cohomology and of…
Non-Douglas-Kazakov phase transition of two-dimensional generalized Yang-Mills theories
M. Khorrami, M. Alimohammadi
In two-dimensional Yang-Mills and generalized Yang-Mills theories for large gauge groups, there is a dominant representation determining the thermodynamic limit of the system. This…
Vanishing of the top local cohomology modules over Noetherian rings
Kamran Divaani-Aazar
Let R be a (not necessarily local) Noetherian ring and M a finitely generated R-module of finite dimension d. Let \fa be an ideal of R and \fM denote the intersection of all prime…
Generalized local cohomology and regularity of Ext modules
Marc Chardin, Kamran Divaani-Aazar
Let R be a Noetherian standard graded ring, and M and N two finitely generated graded R-modules. We introduce reg_R (M,N) by using the notion of generalized local cohomology instea…
