David J. Fernández-Bretón, DGAPA Postdoctoral Fellow
Instituto de Matemáticas, Universidad Nacional Autónoma de México
My name is David Fernández
, and I am currently a DGAPA postdoc at the 1 Mathematics Institute of Universidad Nacional Autónoma de México, Mexico City. My main research interests are in set theory, especially forcing, large cardinals, and cardinal characteristics of the continuum, as well as their applications to algebra, analysis, and topology. A considerable chunk of my research work has been centred on the interaction between Hindman's theorem and infinitary combinatorics, both in the countable and in the uncountable realm. A good summary of my research trajectory can be found in the slides for my talk at the BLAST conference.
Before my current position, I spent a few months as a FORDECyT postdoc at the
Centro de Investigación y Estudios Avanzados (Cinvestav); and before that I spent a few months at the Kurt Gödel Research Center for Mathematical Logic in Vienna, where my postdoctoral mentor was Vera Fischer. Before that, for three years I was a postdoc at the University of Michigan, with Andreas Blass as my postdoctoral mentor, and before that, I spent one semester unofficially mentored by Michael Hrušák at Universidad Nacional Autónoma de México. Before all of the postdoc positions, I used to be a PhD student at York University in Toronto, Canada, where my supervisor was Juris Steprāns . Although it is irrelevant, a nice trivia fact is that my 2 Erdős number is 3.
1. My paternal surname is Fernández, and my maternal surname is Bretón; this is a distinction that English-speaking people are not familiar with and therefore they tend to get the whole thing wrong all the time. If you'd like to get it right, go read
the relevant Wikipedia article, especially the "forms of address" subsection; basically, don't ever use "Bretón" unless you're willing to also use "Fernández" at the same time. ↩ 2. If you're interested in these things, you can check out
