Vector interpretation of the matrix orthogonality on the real line
A. Branquinho, F. Marcellán, A. Mendes
In this paper we study sequences of vector orthogonal polynomials. The vector orthogonality presented here provides a reinterpretation of what is known in the literature as matrix…

Scalar-pseudoscalar meson behavior and restoration of symmetries in SU(3) PNJL model
Pedro Costa, M. C. Ruivo, C. A. de Sousa +2
The modification of mesonic observables in a hot medium is analyzed as a tool to investigate the restoration of chiral and axial symmetries in the context of the Polyakov-loop exte…

The QCD critical end point in the PNJL model
Pedro Costa, C. A. de Sousa, M. C. Ruivo +1
We investigate the role played by the Polyakov loop in the dynamics of the chiral phase transition in the framework of the so-called PNJL model in the SU(2)sector. We present the p…
