Abstract
We study the space of non-degenerate traces on quantized Kleinian singularities of type A by studying their complement, the degenerate traces. In particular, we find the dimension of the space of twisted traces as a function of the corresponding automorphism and the quantization parameters, encoded in a polynomial .
