I don't think so. Do you find it strange that it's absence from
HAC didn't stop the rest of us from learning anything about
them?

I didn't ask what you'd guess it means, I asked if you could
find out. Try "one parameter family".

if one has trouble understanding deep theories, then
spending his effort studying the fundamentals is far better
