This math image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with
{{vector version available|new image name}}.
It is recommended to name the SVG file “Mapping cylinder from X to Y.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
 | This image shows some kind of formula that could be converted to TeX. Storing formulas as images makes it harder to change them. TeX also helps making sure that they all use the same font and size.
A replacement has been proposed: In your article, replace the image with: <math>\begin{array}{ccc}
{} & {} & Mf \\
{} & i \nearrow & \left\downarrow \begin{align} \\ r \\ {} \end{align} \right. \\
{X} & \xrightarrow[\quad f \quad]{} & Y
\end{array}</math> |  |
