A classification of Nichols algebras of semisimple Yetter-Drinfeld modules over non-abelian groups
(European Mathematical Society, 2017-02)
Over fields of arbitrary characteristic we classify all braid-indecomposable tuples of at least two absolutely simple Yetter-Drinfeld modules over non-abelian groups such that the group is generated by the support of the ...

The geometry of quadratic polynomial differential systems with a finite and an infinite Saddle-node (A, B)
(World Scientific Publishing CompanySingapore, 2014-04)
Planar quadratic differential systems occur in many areas of applied mathematics. Although more than one thousand papers have been written on these systems, a complete understanding of this family is still missing. Classical ...
Conhecimento simbólico em John Venn
(Universidade Federal de Santa MariaBRFilosofiaUFSMPrograma de Pós-Graduação em Filosofia, 2013-03-08)
This dissertation presents a reconstruction of John Venn s (1834-1923) logical theory
in Symbolic Logic (1881; 1894). In his work, Venn presents an algebra of logic, and faces a
number of philosophical problems underlying ...

Embedding of the vertices of the Auslander-Reiten quiver of an iterated tilted algebra of Dynkin type Δ in ZΔ
(Academic Press Inc Elsevier Science, 2003-07)
Let Δ be a Dynkin diagram and k an algebraically closed field. Let A be an iterated tilted finite-dimensional k-algebra of type Δ and denote by  its repetitive algebra. We approach the problem of finding a combinatorial ...
Incluindo uma política de construção de objetos espaciais fuzzy no pacote FSR
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilEspecialização em Ciência de DadosUTFPR, 2021-12-30)
Currently, geoscientists have shown interest in modeling spatial phenomena with types of imprecise data, thus, fuzzy set theory has been used as a framework to model these types of imprecise data, through fuzzy spatial ...
