WebJan 8, 2024 · If B 2 − 4 A C = 0 B^2 - 4AC = 0 B 2 − 4 A C = 0, only one real characteristic exists, lead to a parabolic PDE. If B 2 − 4 A C < 0 B^2 - 4AC < 0 B 2 − 4 A C < 0: two complex characteristics exist, lead to an elliptic PDE. By the way, using characteristics is a dimensionality reduction.
