Abstract

The ratio of the circumference of a circle to its diameter is constant and its value is the number $\pi=3.14159...$. Here we understand that the circumference and the diameter are calculated with respect to the usual euclidean metric. Instead, we can equip $\R^2$ with some other metric. Choosing the metric $d_p,$ induced by the $p$-norm, the ratio of the circumference to the diameter will also be constant, but its value will be changed. In this paper we discuss $p$-norms and metrics $d_p$, the circles $S_p$ and the numbers $\pi_p$ with respect to these norms.
