1 = λx x T x = 1. (3) It was proved in Qi (2004) that H-eigenvalues and Z-eigenvalues exist for an evenorder real supersymmetric tensor A, and A is positive de?nite if and only if all of its H-eigenvalues (Z-eigenvalues) are positive. Thus, the smallest H-eigenvalue and ...

smallest eigenvaluesWe show the existence of and then compare smallest eigenvalues for Atici–Eloe fractional difference equations satisfying a right focal boundary condition. The theory of u0-positive operators is applied to obtain these results.doi:10.1080/10236198.2017.1321641Henderson, Johnny...

Explicit formulas for calculating eigenvalues of the Hankel circulants, Hankel skewcirculants, (T + H)-circulants, and (T + H)-skew-circulants are obtained. It is shown that, if ϕ ≠±1, then the set of matrices that can be represented as sums of a Toeplitz ϕ-circulant and a ...

In pulsed neutron experiments, the time decay of a short neutron pulse introduced at t = 0 is observed using neutron detectors. The initial shape of the pulse at t = 0 can be considered to be a linear combination of various α-eigenfunctions. Each α-eigenfunction decays at its ...
Namely, considering a bilinear control system of the form $u_t-\Delta u=\mathcal V u$, $\mathcal V=\mathcal V(t,x)$ being the control, can we give qualitative information, under $L^\infty$ and $L^1$ constraints on $\mathcal V$, on the solutions of the optimisation problem $...
