This is a pretty curved surface, but I have not found many explanations. In differential equations,Breather SurfaceIs a mathematical surface relating to breathers. The mathematical formula is complex. The parameter equation is: Where 0

The curved surface generated when the hyperbolic curve rotates around its symmetric axis is a bilinear surface. In mathematics, Hyperbolic SurfaceIs a quadratic surface. The single-leaf dual-surface can be expressed in the formula (x ^ 2)/(a ^ 2) + (
