In 2013, Gau and Wu introduced a unitary invariant, denoted by k ( A ) , of an n × n matrix A, which counts the maximal number of orthonormal vectors x j such that the scalar products 〈 A x j , x j 〉 lie on the boundary of the numerical range W

We present a simple mathematical model of the development and progression of breast cancer based on evolutionary game theory. Four types of cellular populations are considered: stromal (native) cells, macrophages, benign tumor cells, and motile (mali

For a given n × n matrix A, let k ( A ) stand for the maximal number of orthonormal vectors x j such that the scalar products 〈 A x j , x j 〉 lie on the boundary of the numerical range W ( A ) . This number was recently introduced by Gau and Wu

This paper discusses various constitutive restrictions on the strain energy function for an isotropic hyperelastic material derived from the condition of strong ellipticity. The strain energy function is assumed to be a function of a novel set of inv

According to Kippenhahn's classification, numerical ranges W(A) of unitarily irre- ducible 3 × 3 matrices A come in three possible shapes, an elliptical disk being one of them. The known criterion for the ellipticity of W(A) consists of several equa

This report summarizes the progress made in developing the theoretical underpinnings for two new theories of brittle fracture. One is based upon an extension of continuum mechanics to the nano-scale while the second is based upon a strain limited con
