In differential geometry, a breather surface is a one-parameter family of mathematical surfaces which correspond to breather solutions[1] of the sine-Gordon equation, a differential equation appearing in theoretical physics. The surfaces have the remarkable property that they have constant curvature , where the curvature is well-defined. This makes them examples of generalized pseudospheres.
