Riemann Surfaces

Examples


The following are some examples of multiple-valued functions. In each case, the branch is identified with a different color. Click on the following functions or scroll down to explore.

\(f(z) = z^{1/2}\)     \(f(z) = z^{1/3}\)     \(f(z) = \sqrt{1-z^2}\)     \(f(z) = \dfrac{1}{\sqrt{1-z^2}}\)     \(f(z) = \arctan(z)\)



Real component of \(f(z)=z^{1/2}\)




Imaginary component of \(f(z)=z^{1/2}\)
