Congratulations to Hernando Bermudez, who has started work at Microsoft in Bellevue, Washington! Hernando received his PhD in mathematics and a master’s in computer science from Emory in August 2014, along the way writing three papers: Linear preservers and representations with 1-dimensional ring of invariants (preprint) (journal), with Victor Larsen and me, Transactions of the AMS 366 #9 (2014), 4755-4780…
Come see Hernando Bermudez’s poster on our joint paper Linear preservers and representations with a 1-dimensional ring of invariants at MathFest.
New paper from my group: Degree 3 cohomological invariants of groups that are neither simply connected nor adjoint. [arxiv.org:1305.2899]
Come see my student Chen Chen defend his senior thesis tomorrow 4/10 at 4pm on lognormal vs hyperbolic distributions in finance.
