A One-dimensional Embedding Complex
نویسنده
چکیده
We give the first explicit computations of rational homotopy groups of spaces of “long knots” in Euclidean spaces. We define a spectral sequence which converges to these rational homotopy groups whose E term is defined in terms of braid Lie algebras. For odd k we establish a vanishing line for this spectral sequence, show the Euler characteristic of the rows of this E term is zero, and make calculations of E in a finite range.

Combination of Adaptive-Grid Embedding and Redistribution Methods on Semi Structured Grids for two-dimensional invisid flows
Among the adaptive-grid methods, redistribution and embedding techniques have been the focus of more attention by researchers. Simultaneous or combined adaptive techniques have also been used. This paper describes a combination of adaptive-grid embedding and redistribution methods on semi-structured grids for two-dimensional invisid flows. Since the grid is semi-structured, it is possible to us...
متن کاملLink Prediction using Network Embedding based on Global Similarity
Background: The link prediction issue is one of the most widely used problems in complex network analysis. Link prediction requires knowing the background of previous link connections and combining them with available information. The link prediction local approaches with node structure objectives are fast in case of speed but are not accurate enough. On the other hand, the global link predicti...

متن کاملOne-dimensional Uranium(VI) Coordination Polymer Complex Containing Dimethyl and Trimethyl Phosphate Ligands: Synthesis, Spectroscopic Characterization, Thermal Analyses, and Crystal Structure
A new one-dimensional uranium(VI) coordination polymer, [UO2(μ-DMP)2(TMP)]n (1) (DMP is dimethyl phosphate and TMP is trimethyl phosphate), was prepared from the reaction of UO2(NO3)2.6H2O and TMP in in THF (THF is tetrahydrofuran) as a solvent. Suitable crystals of this complex for crystal structure determination were obtained by slow evaporation of the produced yellow solution at room tempera...
متن کاملSome new exact traveling wave solutions one dimensional modified complex Ginzburg- Landau equation
In this paper, we obtain exact solutions involving parameters of some nonlinear PDEs in mathmatical physics; namely the one-dimensional modified complex Ginzburg-Landau equation by using the $ (G'/G) $ expansion method, homogeneous balance method, extended F-expansion method. By using homogeneous balance principle and the extended F-expansion, more periodic wave solutions expressed by j...
متن کاملSecurity, confidentiality, and privacy of information in the field of health with data EPR embedding in medical MRI images based on HVS model
the development of new technology and modern equipment has led to the development of telemedicine systems. As a result, there are dangers such as publishing patient information and intentionally or unintentionally, medical information. The forensic organization, as one of the powerful arms of the judiciary, pursues important cases in the medical and psychiatric commissions to take steps to rea...
