Riemann Surface A Riemann surface is a surface-like configuration that covers the complex plane with several, and in general infinitely many, "sheets." These sheets can have very complicated structures and interconnections (Knopp 1996, pp. 98-99). Riemann surfaces are one way of representing multiple-valued functions. A Riemann surface is a manifold of (real) dimension two â&#x20AC;&#x201C; a surface â&#x20AC;&#x201C; together with a conformal structure. Again, manifold means that locally at any point x of X, the space is supposed to be like the real plane. The supplement "Riemann" signifies that X is endowed with an additional str ucture which allows angle measurement on the manifold, namely an equivalence class of so-called Riemannian metrics. Two such metrics are considered equivalent if the angles they measure are the same. Choosing an equivalence class of metrices on X is the additional datum of the conformal structure.

Tensed Structures Snd Session used functions (tan,tan) Riemann Surfaces of Inverses of Sums of Two Trigonometric Functions The graphic shows some sheets of the Riemann surface of for inverses of sums of trigonometric functions Subscript[f, 1] and Subscript[f, 2] . For purely real or imaginary parts (\[Alpha]=0 or \[Alpha]=1), multiple sheets can degenerate into a single sheet. Model Starting form the RIEMANN SURFACE graphics made in Mathematica we chose one of the solutions[tan,tan] and reproduced it in a physical model by using a cilindrical surface and 2 V CUTS

Tensile Riemann

We started from a Riemann minimal surface and we modified it. We have made several modules on which we have applied different tensile forces...
