I found another news story in Spanish, which I understand
a little bit. The details I got amount to this:
"en su investigación fue abordar el problema "desde el punto de vista de
la variable compleja de la teoría de funciones", ya que este es un
teorema "clásico" en teoría de operadores en análisis funcional."
"variable compleja de la teoría de funciones" = complex variables,
function theory ?
That's all I found on the math. side.
