Romanovski polynomials, Gegenbauer connections, and $su (1, 1)$ ladder structures

José A. Vallejo, Mariana Kirchbach

We study the monic Romanovski (pseudo-Jacobi) polynomials corresponding to the degree dependent parameters $β_{K} = - K$ , $α_{K} = c / (K + 1)$ , with $K = n + ℓ$ . We write down, in explicit form…

Potentials on the conformally compactified Minkowski spacetime and their application to quark deconfinement

M. Kirchbach, J. A. Vallejo

We study a class of conformal metric deformations in the quasi-radial coordinate parameterizing the 3-sphere in the conformally compactified Minkowski spacetime $S^{1} \times S^{3}$ . Pr…
