description of the asymptotic behavior of the celebrated Nonabelian Hodge
correspondence. In particular, it is expected that the dual boundary complex of
the compactification of character varieties has the homotopy type of a sphere.
In a joint work with Enrica Mazzon and Matthew Stevenson, we compute the first
non-trivial examples of these dual boundary complexes in the compact case. This
requires to develop a new theory of essential skeletons over a trivially-valued
field. As a byproduct, inspired by these constructions, we show that certain
character varieties appear in degenerations of compact hyper-Kähler 
manifolds.  In this talk I will explain how these new non-archimedean
techniques can shed new light into classical algebraic geometry problems.</span><span lang="EN-US" style="font-size:16pt;font-family:"Times New Roman",serif"></span></p>
