On Finite Matrix Bi-Dimensional Formulation of Classical Field Models
L. P. Colatto, A. L. A. Penna, C. M. M. Polito
We introduce a basis for a bi-dimensional finite matrix calculus and a bi-dimensional finite matrix action principle. As an application, we analyze scalar and spinorial fields in $…

The Central Charge in 3D Simple Superalgebra
L. P. Colatto
A matter self-interacting model with N=1-supersymmetry in 3D is discussed in connection with the appearance of a central charge in the algebra of the supersymmetry generators. The…

Matrix-Spacetimes and a 2D Lorentz-Covariant Calculus in Any Even Dimension
L. P. Colatto, M. A. De Andrade, F. Toppan
A manifestly Lorentz-covariant calculus based on two matrix-coordinates and their associated derivatives is introduced. It allows formulating relativistic field theories in any eve…
