    • Meromorphic functions on germs of surfaces along a rational curve 

      Falla Luza, Maycol (Pontificia Universidad Católica del PerúPE, 2023-12-29)
      We give examples of germs of surfaces containing a rational curve with positive self-intersection and with zero, one or two independent meromorphic functions.

    • Categoría de una aplicación y análisis no lineal 

      Ipanaque Zapata, Cesar A. (Pontificia Universidad Católica del PerúPE, 2023-12-29)
      A classic problem in analysis is to solve nonlinear equations of the form F (x) = 0, where F : Dn → Rm is a continuous map of the closed unit disk Dn ⊂ Rn in Rm. A topological technique, which exists in the literature, ...

    • Solución de sistemas lineales singulares basada en minimización 

      Casavilca, Juan E. (Pontificia Universidad Católica del PerúPE, 2023-12-29)
      This article introduces a new concept of solution of a linear singular system (descriptor system), based on minimization. It is shown that, by imposing a hypothesis on the matrices of the descriptor system, the minimization-based ...
