Groups of Orthogonal Matrices All Orbits of Which Generate Lattices,se groups are irreducible: the two trivial groups in one dimension, the cyclic groups of orders 3, 4, 6 in two dimensions, and the quaternion, binary dihedral, binary tetrahedral groups in four dimensions.

,-Inner Functions and ,-Contractions, extend a uniqueness theorem of Arveson for minimal .-dilations to our setting. We thus generalize results of Olofsson for .-hypercontractions on the unit disc and of the first named author for .-hypercontractions on the unit ball.

A Note on Group Representations, Determinantal Hypersurfaces and Their Quantizations,his short note solves three problems about extending this result in the negative. On the affirmative side, it is shown that a quantization of a determinantal hypersurface, the so-called free locus, correlates well with representation theory. If . generate a finite group ., then the family of hypersurfaces . for . determines . up to isomorphism.

Extended Heinz and Jensen Type Inequalities and Rearrangements,cal order rearrangement of a given set ., .. > 0, . = 1, 2, …, .. These lead to extended Heinz type inequalities of . for different intervals of .. The results may also be considered as special cases of Jensen type inequalities for concave, convex, subquadratic and superquadratic functions, which are also discussed in this paper.

The Inverse Characteristic Polynomial Problem for Trees,an ten vertices. It also includes the known case of polynomials with distinct real roots for any tree (in a new way). This work is motivated by, and lies in contrast to, the considerable study of possible multiplicity lists for the eigenvalues of real symmetric matrices, whose graph is a tree.
