Recently, André verified the existence of a Big Cohen Macaulay algebra for a complete local ring of mixed characteristic by using the theory of perfectoid. On the other hand, Liedtke, Martin and Matsumoto conjectured that linearly reductive quotient singularities are stable under deformations over a local ring of mixed characteristic. In this talk, we apply André's result and give an affirmative answer to the conjecture. This is joint work with Professor Shunsuke Takagi.
