The complex squaring map \(f(z) = z^2\) "wraps the plane around itself twice" by doubling polar angles at \(0\). The domain plane is at the top, compare our Complex Square Roots products. The image, with a third coordinate added to clarify the mapping, is at bottom. The grid of hyperbolas at the top maps to a square Cartesian grid at bottom. Either surface may be viewed as the Riemann surface of the square root.
Handmade in the UK by specialist picture framers using premium fine art paper with a gently textured surface and satin finish, high-quality wood, and an FSC certified off-white mat. Delivered ready for hanging.
