Extending valuations of local domains to complete local domains without changing the value group
F. J. Herrera Govantes, M. A. Olalla Acosta, M. Spivakovsky +1
Let be an excellent local noetherian domain with field of fractions . Let be a valuation centered at and let be the correspondi…
A hyperbolic proof of Pascal's Theorem
Miguel Acosta, Jean-Marc Schlenker
We provide a simple proof of Pascal's Theorem on cyclic hexagons, as well as a generalization by Möbius, using hyperbolic geometry.
On GIT quotients and real forms
Miguel Acosta
We consider actions of complex algebraic groups on complex algebraic varieties , coming from actions of real forms of and of $\mathbf{…
On the limit set of a spherical CR uniformization
Miguel Acosta
We explore the limit set of a particular spherical CR uniformization of a cusped hyperbolic manifold. We prove that the limit set is the closure of a countable union of $\mathbb{R}…
Character varieties for real forms of classical complex groups
Miguel Acosta
Let be a finitely generated group, be a classical complex group and a real form of . We propose a definition of the -c…
Spherical CR uniformization of Dehn surgeries of the Whitehead link complement
Miguel Acosta
We apply a spherical CR Dehn surgery theorem in order to obtain infinitely many Dehn surgeries of the Whitehead link complement that carry spherical CR structures. We consider as s…
