摘要: M-eigenvalues of elasticity M-tensors play an important role in nonlinear and materials. In this paper, we present several new lower bounds for the minimum M-eigenvalue propose numerical examples to illustrate efficiency obtained results. As applications, provide checkable sufficient conditions strong ellipticity positive definiteness irreducible M-tensors.
