# Are q-additive functions implemented in Sage ? Where ?

Hi,

We are interested in q-additive functions and sequences. This objects are for instance described in "Sur certaines suites uniformement equireparties modulo 1" (Jean Coquet).

We couldn't find these objects implemented in sage (but maybe we did not look well enough).

Could you please tell us whether q-additive functions are implemented in sage or not ? Also, if we do implement something about q-additive functions, in which part of sage would it fit the best.

Let us consider this as reference: Sur certaines suites..., where is the definition of a $q$-additive function / sequence in it?

In the article, this is discussed in paragraph 3.3, with a reference to [3] for a definition.
