Horo-tight spheres in hyperbolic space
(SPRINGER, 2011)
We study horo-tight immersions of manifolds into hyperbolic spaces. The main result gives several characterizations of horo-tightness of spheres, answering a question proposed by Cecil and Ryan. For instance, we prove that ...
Topological games and productively countably tight spaces
(ElsevierAmsterdam, 2014-07-01)
The two main results of this work are the following: if a space X is such that player II has a winning strategy in the game 'G IND.1' ('Ω IND.X', 'Ω IND.X') for every x ∈ X, then X is productively countably tight. On the ...
Almost partitioning 2-edge-colourings of 3-uniform hypergraphs with two monochromatic tight cycles
(Elsevier B.V., 2017)
We show that any 2-colouring of the 3-uniform complete hypergraph Kn (3) on n vertices contains two disjoint monochromatic tight cycles of distinct colours covering all but o(n) vertices of Kn (3). The same result holds ...
Almost partitioning 2-colored complete 3-uniform hypergraphs into two monochromatic tight or loose cycles
(Wiley-Liss Inc., 2019)
© 2018 Wiley Periodicals Inc. We show that for every η > 0 there exists an integer n 0 such that every 2-coloring of the 3-uniform complete hypergraph on n ≥ n 0 vertices contains two disjoint monochromatic tight cycles ...
Wannier functions of cumulene: A tight-binding approach
(Wiley-Blackwell, 2016-03-01)
Exponentially localized Wannier functions of cumulene are calculated from the Bloch functions obtained through a tight-binding approach. Numerical results and discussions are given for the pi and sigma bands. In the latter ...
Thirteen-band tight-binding model for the MoS2 monolayer
(2021-01-01)
A tight-binding model is fitted to density-functional calculations of the electronic structure of the MoS2 monolayer. The model involves 13 atomic orbitals per unit cell: the 4d orbitals of the molybdenum atom plus the 3s ...
Partitioning edge-colored hypergraphs into few monochromatic tight cycles
(Siam, 2020)
Confirming a conjecture of Gyarfas, we prove that, for all natural numbers k and r, the vertices of every r-edge-colored complete k-uniform hypergraph can be partitioned into a bounded number (independent of the size of ...

Influência do Propante de Fraturamento Hidráulico na Produção de Reservatório Tight Gas
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de Petróleo, 2017-11-22)
The increasing global energetic demand forces the researchers to search for new extraction approaches of oil resources, inducing the industry to invest in the production of unconventional reservoirs, which access is more ...
Efficient Tight Field Bounds Computation Based on Shape Predicates
(Springer, 2014-05)
Tight field bounds contribute to verifying the correctness of object oriented programs in bounded scenarios, by restricting the values that fields can take to feasible cases only, during automated analysis. Tight field ...
