 Laplacians, multivariate extremes and algebraic statistics (November 48, 2024), Eindhoven, The Netherlands.
 I am looking for graduate students interested in mathematical statistics and its aspects related to combinatorics, convex analysis, and tensors. For recent PhD graduates: There is a number of open calls for postdoctoral positions at UofT  see here, here, here, here, and here (the latter is particularly suitable for underrepresented groups).
 GOLAZO R package for a general assymetric regularization of the loglikelihood in Gaussian graphical models.
To install, just call

Math to the people (four axioms of Federico Ardila):
 Axiom 1. Mathematical potential is distributed equally among different groups, irrespective of geographic, demographic, and economic boundaries.
 Axiom 2. Everyone can have joyful, meaningful, and empowering mathematical experiences.
 Axiom 3. Mathematics is a powerful, malleable tool that can be shaped and used differently by various communities to serve their needs.
 Axiom 4. Every student deserves to be treated with dignity and respect.
