We introduce the notion of strictly systolic angled complexes. They generalize Januszkiewickz and \'Swi\k{a}tkowski's $7$-systolic simplicial complexes also their metric counterparts, which appear as natural analogues to Huang Osajda's metrically in context negative curvature. prove that groups act on them geometrically, together with finitely presented subgroups, are hyperbolic. use these stud...

Esta conversa com o Professor Carlos Roberto Jamil Cury relator do famoso Parecer CNE/CEB nº 11/2000 que estabeleceu as “Diretrizes Curriculares Nacionais para a Educação de Jovens e Adultos”, ocorre como marco dos 20 anos aprovação das Diretrizes este dossiê temático e-Mosaicos. Trata-se um diálogo sobre documento contribuiu delinear importantes conquistas no campo da EJA nos subsequentes aind...

We investigate systems of equations and the first-order theory one-relator monoids. describe a family F monoids form 〈A|w=1〉 where for each monoid M in F, longstanding open problem decidability word with length constraints reduces to Diophantine (i.e. equations) M. achieve this result by finding an interpretation free monoid, using only together relations. It follows that has undecidable positi...

If G is a word hyperbolic group of cohomological dimension 2, then every subgroup of G of type FP2 is also word hyperbolic. Isoperimetric inequalities are denned for groups of type FP2 and it is shown that the linear isoperimetric inequality in this generalized context is equivalent to word hyperbolicity. A sufficient condition for hyperbolicity of a general graph is given along with an applica...
