Cooperative Sheaf Neural Networks
André Ribeiro, Ana Luiza Tenório, Juan Belieni +2
Sheaf diffusion has recently emerged as a promising design pattern for graph representation learning due to its inherent ability to handle heterophilic data and avoid oversmoothing…
Grothendieck prelopologies: towards a closed monoidal sheaf category
Ana Luiza Tenório, Hugo Luiz Mariano
In this paper, we present a generalization of Grothendieck pretopologies -- suited for semicartesian categories with equalizers -- leading to a closed monoidal category of shea…
Expanding Čech cohomology for quantales
Ana Luiza Tenório, Peter Arndt, Hugo Luiz Mariano
We expand Čech cohomology of a topological space with values in a presheaf on to Čech cohomology of a commutative ring with unity with values in a presheaf on . The…
The Category of Hypergroups: seeking for a generalized version of Abelian Categories
Kaique Matias de Andrade Roberto, Ana Luiza Tenório
In this paper we study categorical properties of the category of abelian hypergroups that leads to the notion of hyper (almost) preadditive and hyper (almost) abelian categories. O…
On sheaves on semicartesian quantales and their truth values
Ana Luiza Tenório, Caio de Andrade Mendes, Hugo Luiz Mariano
In this paper, we introduce a new definition of sheaves on semicartesian quantales, providing first examples and categorical properties. We note that our sheaves are similar to the…
Zeta Function Method for Repulsive Casimir Forces at Finite Temperature
F. C. Santos, A. Tenório, A. C. Tort
We compute the Casimir energy between an unusual pair of parallel plates at finite temperature, namely, a perfectely conducting plate () and an infinitely permeable one…
