Covariant hamiltonian for gravity coupled to -forms
Leonardo Castellani, Alessandro D'Adda
We review the covariant canonical formalism initiated by D'Adda, Nelson and Regge in 1985, and extend it to include a definition of form-Poisson brackets (FPB) for geometric theori…
Quaternion based generalization of Chern-Simons theories in arbitrary dimensions
Alessandro D'Adda, Noboru Kawamoto, Naoki Shimode +1
A generalization of Chern-Simons gauge theory is formulated in any dimension and arbitrary gauge group where gauge fields and gauge parameters are differential forms of any degree.…
Formulation of Supersymmetry on a Lattice as a Representation of a Deformed Superalgebra
Alessandro D'Adda, Noboru Kawamoto, Jun Saito
The lattice superalgebra of the link approach is shown to satisfy a Hopf algebraic supersymmetry where the difference operator is introduced as a momentum operator. The breakdown o…
A new large N phase transition in YM2
A. Apolloni, S. Arianos, A. D'Adda
Inspired by the interpretation of two dimensional Yang-Mills theory on a cylinder as a random walk on the gauge group, we point out the existence of a large N transition which is t…
Two-dimensional gauge theories of the symmetric group S(n) and branched n-coverings of Riemann surfaces in the large-n limit
A. D'Adda, P. Provero
Branched n-coverings of Riemann surfaces are described by a 2d lattice gauge theory of the symmetric group S(n) defined on a cell discretization of the surface. We study the theory…
Two-dimensional gauge theories of the symmetric group S_n in the large-n limit
A. D'Adda, P. Provero
We study the two-dimensional gauge theory of the symmetric group S_n describing the statistics of branched n-coverings of Riemann surfaces. We consider the theory defined on the di…
