A torus is a doughnut-shaped geometric surface created by rotating a circle around an axis, and it can take different forms depending on how far the circle is from that axis. Mathematicians study tori because they are fundamental shapes that appear in geometry and can transform into other shapes, such as spheres, by changing their dimensions.

In geometria il toro (dal latino torus, cuscino a forma di ciambella) è una superficie di rotazione ottenuta dalla rivoluzione di una circonferenza in uno spazio tridimensionale intorno a un asse ad essa complanare.
