    • BASES FOR QUANTUM ALGEBRAS AND SKEW POINCARÉ-BIRKHOFF-WITT EXTENSIONS 

      Reyes, Armando; Suárez, Héctor
      Considering quantum algebras and skew Poincaré-Birkhoff-Witt (PBW for short) extensions defined by a ring and a set of variables with relations between them, we are interesting in finding a criteria and some algorithms ...

    • Calabi-Yau property for graded skew PBW extensions 

      Suárez, Héctor; Lezama, Oswaldo; Reyes, Armando
      Graded skew PBW extensions were defined by the first author as a generalization of graded iterated Ore extensions [36]. The purpose of this paper is to study the Artin-Schelter regularity and the (skew) Calabi-Yau condition ...

    • Microstructural changes and the effect on myofibril proteins in yamu (Brycon amazonicus) fish meat during cold storage 

      Castañeda, Daniel; Lozano, José Manuel; Suárez, Héctor
      This study aimed to evaluate the effect of cold storage on yamu fish meat (Brycon amazonicus). The methodology consisted of analyzing two temperatures (0�}1.6°C and -8�}1°C), two storage periods (13 and 61 hours) and two ...
