MathematicsIn this work, we construct a homotopy theory for a class of intersection graphs arising from topological monoids. We introduce the M-intersection graph of a τe-monoid, where the vertices correspond to proper τe-submonoids and adjacency is defined by ...

Acta Scientiarum: Technology, 2013 Higher homotopy of graphs has been defined in several articles. However, the existence of a long exact sequence associated to a pair (G, A) has not been touched at. We treat it here.

INDEX COMPUTATION OF SOME BISINGULAR OPERATORS WITH SHIFT BY HOMOTOPY METHOD
Вестник Донского государственного технического университета, 2018 The work continues to research the insufficiently explored problem of bisingular operators with shift index. It considers new cases of index computation of the bisingular operators with indisintegrative involutive shift by the homotopy method.

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria MatematicaThis paper presents Leray–Schauder alternatives and a topological transversality (homotopy) theorem for compact upper semicontinuos maps having (strongly) convexly totally bounded ranges.

Anaphores, stratégies discursives et genres textuels [PDF]
Echo des Etudes Romanes, 2012 In this paper, we start with the fact that every text presents a dominating shape of anaphoric relations. We wish to experiment the communicative dynamism of anaphora in two text genres: scientific written one versus essay.

On bifurcation points of strongly condensing operators
Научный вестник МГТУ ГА, 2016 Two conditions equivalent to complete continuity of Frechet derivative at a point and the asymptotic derivative in the case of their existence are given. Theorem of M.A. Krasnosel’skii on asymptotic bifurcation points for completely con-tinuous fields to

Topological Algebra and its Applications, 2017 Let R be an open equivalence relation on a topological space E. We define on E a new equivalence relation ̃ℜ̅ by x̃ ̃ℜ̅y if the closure of the R-trajectory of x is equal to the closure of the R-trajectory of y.

Nadler and Kannan Type Set Valued Mappings in M-Metric Spaces and an Application
Mathematics, 2019 This article intends to initiate the study of Pompeiu–Hausdorff distance induced by an M-metric. The Nadler and Kannan type fixed point theorems for set-valued mappings are also established in the said spaces.

Elliptic systems at resonance for jumping non-linearities
Electronic Journal of Differential Equations, 2016 In this article, we study the existence of nontrivial solutions for the problem $$\displaylines{ -\Delta u=\alpha _1u^{+}-\beta _1u^{-}+f(x,u,v)+h_1( x) \quad \text{in }\Omega, \cr -\Delta v=\alpha _2v^{+}-\beta _2v^{-}+g(x,u,v)+h_2( x) \quad \text ...
