Many rings and algebras arising in quantum mechanics, algebraic analysis, and non-commutative algebraic geometry can be interpreted as skew PBW (Poincare- Birkhoff Witt) extensions. In the present paper we study two aspe...

In the paper Busaniche and Cignoli (2009) we presented a quasivariety of commutative residuated lattices, called NPc-lattices, that serves as an algebraic semantics for paraconsistent Nelson's logic. In the present paper...

The “time-and-band limiting” commutative property was found and exploited by D. Slepian, H. Landau and H. Pollak at Bell Labs in the 1960´s, and independently by M. Mehta and later by C. Tracy and H. Widom in Random...

An l-hemi-implicative semilattice is an algebra A=(A,∧,→,1) such that (A,∧,1) is a semilattice with a greatest element 1 and satisfies: (1) for every a,b,c∈A , a≤b→c implies a∧b≤c and (2) a...

En esta tesis introducimos el concepto de estructlltr's covariantes {(d, "), (a, n), (a, d)} formadas por una C*-algebra "cy' separable, una acción torcida medible (a, a) de un gnrpo localmente compacto segundo-contab...

En esta tesis investigamos la clase de los qM3 retículos y la de los mM3−retículos o M3−retículos monádicos, que son M3−retículos dotados de un cuantificador existencial, en el primer caso, y en el segundo d...

Abstract We reconsider in modern terms the old discovery by A. Kirillov and M. Noumi, who devised peculiar operators adding columns to Young diagrams enumerating the Schur, Jack and Macdonald polynomials. In this sense, ...
