Ordinary representation and cohomology

We can associate \(p\) -adic admissible unitary representation of \(\GL_2(\Q_p)\) to every local Galois representation. We prove if local Galois representations is ordinary then there exists a sub representation of this representation of \(\GL_2(\Q_p)\) that appears in ordinary parts of the cohomolo...

description We can associate \(p\) -adic admissible unitary representation of \(\GL_2(\Q_p)\) to every local Galois representation. We prove if local Galois representations is ordinary then there exists a sub representation of this representation of \(\GL_2(\Q_p)\) that appears in ordinary parts of the cohomology. We give a positive answer to a question raised by Chojecki \cite{Chojecki18}.
