In a wide range of applications,the model reduction techniques provide a well-established tool for efficient approximation of the transfer functions of larg
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
