Companion points on the eigenvariety with non-regular weights

Abstract

We prove the existence of all companion points on the eigenvariety of definite unitary groups associated with generic crystalline Galois representations with possibly non-regular weights under the Taylor-Wiles hypothesis, based on the previous results of Breuil-Hellmann-Schraen in arXiv:1702.02192 in regular cases and the author in arXiv:2103.03823 in non-regular cases.
