Definition:Continued Fraction/Simple/Infinite

Definition

Let $\R$ be the field of real numbers.

A simple infinite continued fraction is a infinite continued fraction in $\R$ whose partial quotients are integers that are strictly positive, except perhaps the first.

That is, it is a sequence $a : \N_{\geq 0} \to \Z$ with $a_n > 0$ for $n >0$.

Also known as

A simple infinite continued fraction can be abbreviated SICF. It is also known as a regular infinite continued fraction.
