Abstract
We prove that level Witten-Reshetikhin-Turaev quantum representations, also known as the Fibonacci representations, of mapping class groups are locally rigid. More generally, for any prime level , we prove that the level quantum representations are locally rigid on all surfaces of genus if and only if they are locally rigid on surfaces of genus with at most boundary components. This reduces local rigidity in prime level to a finite number of cases.
