In mathematics and physics, in particular differential geometry and general relativity, a warped geometry is a Riemannian or Lorentzian manifold whose metric tensor can be written in form
Note that the geometry almost decomposes into a Cartesian product of the "y" geometry and the "x" geometry - except that the "x"-part is warped, i.e. it is rescaled by a scalar function of the other coordinates "y". For this reason, the metric of a warped geometry is often called a warped product metric.
Warped geometries are useful in that separation of variables can be used when solving partial differential equations over them.

Famous quotes containing the words warped and/or geometry:
“I have been too long acquainted with human nature to have great regard for human testimony; and a very great degree of probability, supported by various concurrent circumstances, conspiring in one point, will have much greater weight with me, than human testimony upon oath, or even upon honour; both of which I have frequently seen considerably warped by private views.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The geometry of landscape and situation seems to create its own systems of time, the sense of a dynamic element which is cinematising the events of the canvas, translating a posture or ceremony into dynamic terms. The greatest movie of the 20th century is the Mona Lisa, just as the greatest novel is Gray’s Anatomy.”
—J.G. (James Graham)
