Spacetime parameter

In pilitron physics, the spacetime parameter, denoted $$\bar{s}$$, is, in simple difinition, the product of the volume and time parameters:


 * $$\bar{s} = \bar{v}\bar{t}$$

But when the volume changes over time, then the spacetime parameter must be defined as the sum of volumes in each time frame from a to b:


 * $$\bar{s} = \sum_{t=a}^{b} \bar{v}_t$$

But when the given volume of space returns to the same states over regular periods of time, then the spacetime parameter can also be divided by the number of occurrences of a repeated state, n:


 * $$\bar{s} = \frac{1}{n+1} \sum_{t=a}^{b} \bar{v}_t$$
