Krall--type Orthogonal Polynomials in several variables
Lidia Fernandez, Teresa E. Perez, Miguel A. Pinar +1
For a bilinear form obtained by adding a Dirac mass to a positive definite moment functional in several variables, explicit formulas of orthogonal polynomials are derived from the…
Orthogonal polynomials and partial differential equations on the unit ball
Miguel Pinar, Yuan Xu
Orthogonal polynomials of degree with respect to the weight function on the unit ball in $\RR^d$ are known to satisfy the partial differential equation…
Some thoughts about matrix coordinate transformations
J. Adam, B. Janssen, W. Troost +1
Matrix coordinate transformations are defined as substitution operators without requiring an ordering prescription or an inclusion function from the Abelian coordinate transformati…
Some remarks on Causality Theory and Variational Methods in Lorentzian manifolds
Miguel Sanchez
In this conference published in 1997 some problems on the geodesics of a Lorentzian manifold concerning causality and infinite-dimensional variational methods, are pointed out. Eve…
The causal boundary of wave-type spacetimes
José Luis Flores, Miguel Sánchez
A complete and systematic approach to compute the causal boundary of wave-type spacetimes is carried out. The case of a 1-dimensional boundary is specially analyzed and its critica…
Deuteron form factors in chiral effective theory: regulator-independent results and the role of two-pion exchange
M. Pavon Valderrama, A. Nogga, E. Ruiz Arriola +1
We evaluate the deuteron charge, quadrupole, and magnetic form factors using wave functions obtained from chiral effective theory (ET) when the potential includes one-pion excha…
