Suborthogonality and Orthocentricity of Matrices
We present some results on submatrices of orthogonal and unitary matrices and their relation to so called orthocentric matrices. These are then completely characterized....

Matrices and Graphs in Geometry
Simplex geometry is a topic generalizing geometry of the triangle and tetrahedron. The appropriate tool for its study is matrix theory, but applications usually involve solving huge systems of linear equations or eigenvalue problems, and geo...

Orthocentral quadrilaterals and their properties
We start the article with already known theorem: Let a quadrilateral ABCD be given in the plane. Construct the orthocenters Ha,Hb, Hc, and Hd, of triangles BCD, ACD, ABD and ABC. Then the quadrilateral has the same area as the quadrilateral ABCD...

Some Results on Combined Matrices
A combined matrix of a nonsingular matrix is the Hadamard (entrywise) product of the matrix and its transposed inverse. A characterization of the diagonal entries of the combined matrix of a positive definite m...

Neutrino Mixing Matrix in Terms of Neutrino Mass Matrix and Its Frobenius Covariants
An explicit expression is derived for the mixing matrix of Majorana neutrinos in terms of the mass matrix and its Frobenius covariants. Illustrative scenarios are taken as examples where the suggested formula is used to obtain the m...

Combined matrices in special classes of matrices
The combined matrix of a nonsingular matrix A is the matrix A o (A(-1))(T), where o means the Hadamard (entrywise) product. It has simple properties, its row- as well as column-sums are always one, and it is not changed if ...
