# A matter of terms

#### yetar

If I have a cyclic space, [0, 1] where 0 is equal to 1.
Can I also call it a cyclic dimension?
What are the terms of describing this cyclic interval/space etc?

Thank you.

Oops, perhaps it should be called cyclic field.
But can I also call it cyclic space or cyclic dimension?

You're talking about R/Z. The reals modulo the integers. It can be identified with the unit circle in the complex plane by $t \to \exp(2\pi t)$.
