Some context. While working on a larger proof, I needed to show that a particular homogeneous system of polynomial equations had no rational solution except for the trivial one. I have reduced this task to the following problem, and if the polynomial stated below has no rational root, it's over...

Can someone point me to an article or textbook where I can learn more about the reduction technique used in the third answer titled Rational Root Theorem Solution to the question asked in Factorization of quartic polynomial.? The key point that interests me in that answer was how the potential q...

I have been trying to understand the connection between Virasoro algebras and CFT. After a course in string theory, I was under the impression that the Virasoro algebra was simply the Lie algebra of the conformal group, but that is not the case. I would like to get an overview of what is going on...
