Note … WebMar 2, 2024 · Having a solution over the reals is equivalent to say that b, c, d are not all > 0. For the p -adic case, it depends on the determinant and local Hasse invariants of the rational quadratic form x 2 + b y 2 + c z 2 + d t 2. Here, the determinant is the square class of b c d, and if p is prime , the local Hasse invariant is ( b, c d) p ( c, d) p.
