comment Normal Operators: Backtransform
I thought the word backtransform was funny; that does not prevent it from being a commonly used word in mathematics, of course. Also, there is a new television series called Backstrom, based on the main character of that book.

comment Squarefree products of a class of primes
Sure. See proof method in volume 2 of LeVeque Topics in Number Theory. The connection with quadratic forms is that the set of "bad" primes is those for which $(\Delta|q) = -1.$ This reduces to representations by a single form with class number one, which happens just a few times for positive forms.
