In this article we characterize the closed cones respectively generated by the symmetric inverse M-matrices and by the inverses of symmetric row diagonally dominant M-matrices. We show the latter has a finite number of ...

Toric dynamical systems are known as complex balancing mass action systems in the mathematical chemistry literature, where many of their remarkable properties have been established. They include as special cases all ...

Recently Sahoo and Sen obtained a series of remarkable results concerning subleading soft photon and graviton theorems in four dimensions. Even though the S-matrix is infrared divergent, they have shown that the subleading ...

In this article we study which infinite matrices are potential matrices. We tackle this problem in the ultrametric framework by studying infinite tree matrices and ultrametric matrices. For each tree matrix, we show the ...

Contour integrals of rational functions over (Formula presented.) , the moduli space of n-punctured spheres, have recently appeared at the core of the tree-level S-matrix of massless particles in arbitrary dimensions. The ...

This paper studies a consensus protocol over a group of agents driven by second-order dynamics. The communication among members of the group is assumed to be directed and affected by two rationally independent time delays, ...

En el siguiente trabajo, se realiza la construcción general de la teoría supersimétrica dándose por conocidos los fundamentos en teoría de grupos en relación a grupo de Poincaré y por lo tanto se inicia desde las propiedades ...

We consider a linear algorithm to achieve formation control in a group of agents which are driven by second-order dynamics and affected by two rationally independent delays. One of the delays is in the position and the ...
