Geometric approaches to matrix normalization and graph balancing
Normal matrices, or matrices which commute with their adjoints, are of fundamental importance in pure and applied mathematics. In this paper, we study a natural functional on the space of square complex matrices whose global minimizers are normal ...

Dai–Liao-type Riemannian optimization for solving the Gough–Stewart platform
We introduce a class of Dai–Liao-type Riemannian conjugate gradient (CG) methods that achieve global convergence without relying on the Gauss lemma, typically invoked under strong convexity assumptions.

Central axes and peripheral points in high dimensional directional datasets.
International audienceWe introduce a new notion of central axis for a finite set {a 1 ,. .. , a m } of vectors in R n. In tandem, we discuss different ways of measuring the dispersion of the data points a i 's around the central axis. Finally, we explain

Characterizations of the Solution Sets of Generalized Convex Minimization Problems [PDF]
2000 Mathematics Subject Classification: 90C26, 90C20, 49J52, 47H05, 47J20.In this paper we obtain some simple characterizations of the solution sets of a pseudoconvex program and a variational inequality. Similar characterizations of the solution set of
