Some Criteria for $${\varvec{\mathcal {H}}}$$-Tensors

Abstract: The H-tensor is a new developed concept in tensor analysis and it is an extension of the M-tensor. In this paper, we present some criteria for identifying nonsingular H-tensors and give two numerical examples.

“…Meanwhile, compared with the extensive study of various exact solutions for nonlinear evolution equation, such as soliton solutions and so on, for both discrete and continuous cases, [24][25][26][27][28] the study of interaction solutions has aroused great interest of researchers. [29][30][31][32][33][34] When lump solutions of Eq. (3) is generated through symbolic computations, there is an interesting question that is what kind of interaction solutions can be formulated by combining other kinds of functions?…”

“…Equation () is solved using the split‐step Crank–Nicolson method [30, 31, 34], which in turn is based on the finite difference (FD) method. The basic idea of the FD method is to transform the problem of solving a partial differential equation, linear or non‐linear, into a problem of solving a systems of algebraic equations [29], using the discretization of spatial and temporal domains of the wave function and the substitution of derivatives present in the differential equation by approximations involving only numerical values of the wave function [35].…”

“…Such timescales are incapable of capturing the essential structural relaxations (such as dynamics of nano-cluster formation/ breakage) and for the prediction of robust rheological properties of these systems at realistic temperatures. In recent studies, coarse-grained (CG) models such as dissipative particle dynamics (DPD) [17,18] and united atom model, [12,19] have been explored for different classes of these complex molecules. However, these models are quite simplistic in their description of the molecules and use limited basis set of potential parameters to distinguish between different aromatic or aliphatic moieties in constituent molecules.…”

“…where k is the number of atoms belonging to ellipsoid i and l is that in ellipsoid j. From the same atomistic trajectory, the unit vectors r u ij î ,ˆ, and u ĵ can be computed and the components of the total GB force along the three unit vectors can be evaluated using Equation (17 ,ˆ, and f u ĵ . These forces constitute the set of reference or observed force data against which the CG force field has to be parameterized.…”
