Helical symmetry is invariance under a one-dimensional group of rigid motions generated by a simultaneous rotation around a fixed axis and trans-lation alon
We prove three results.First,we establish convergence of the solutions of the second-grade model to those of the Euler equations provided ν = O(α2),as α
The development of linearizations of matrix polynomials that preserve interesting structures that a matrix polynomial might have has been a very active topi
Networks have been studied extensively in the social sciences.Many real systems can be properly described by complex networks whose nodes represent individu
