In order to study the structure of defects in nematic liquid crystals, we have constructed a numerical procedure that minimizes the Landau-de Gennes free energy model. Using a new representation, a finite-element discretization, and a direct minimiza

An $n \times n$M-matrix A is said to admit an $LU$ factorization into $n \times n$M-matrices if A can be expressed as $A = LU$ where L is an $n \times n$ lower triangular M-matrix and where U is an upper triangular M-matrix. Then, for any given $n \t

Consider, as nodes for polynomial interpolation, the nth roots of unity. For a sufficiently smooth function f ( z ) f(z) , we require a polynomial p ( z ) p(z) to interpolate f and certain of its derivatives at each node. It is shown that the so-call
