{\Large\bfseries Hindman’s theorem and uncountable groups\par}
\bigskip

\end{center}
\vfill

\textsc{Abstract:}
In the early 1970’s, Hindman proved a beautiful theorem in 
additive Ramsey theory asserting that for any partition of the set of 
natural numbers into finitely many cells, there exists some infinite set 
such that all of its finite sums belong to a single cell.

In this talk, we shall address generalizations of this statement to the 
realm of the uncountable. Among others, we shall present a new theorem 
concerning the real line which simultaneously generalizes a recent 
theorem of Hindman, Leader and Strauss, and a classic theorem of Galvin 
and Shelah.

This is joint work with David Fernandez-Breton.
