Lognormal Distributions and Geometric Averages of Positive Definite Matrices
Armin Schwartzman
This article gives a formal definition of a lognormal family of probability distributions on the set of symmetric positive definite (PD) matrices, seen as a matrix-variate extensio…

Scaling-rotation distance and interpolation of symmetric positive-definite matrices
Sungkyu Jung, Armin Schwartzman, David Groisser
We introduce a new geometric framework for the set of symmetric positive-definite (SPD) matrices, aimed to characterize deformations of SPD matrices by individual scaling of eigenv…

Multiple Testing of Local Maxima for Detection of Peaks in Random Fields
Dan Cheng, Armin Schwartzman
A topological multiple testing scheme is presented for detecting peaks in images under stationary ergodic Gaussian noise, where tests are performed at local maxima of the smoothed…
