Derivation of convergence criterion for $\prod(1+|a_n|)$ from criterion for $\prod(1+a_n)$.

79 Views Asked by At

If we know the following convergence criteria for infinite products is correct

$$\boxed{\sum a_{n}\text{ converges }\Leftrightarrow\prod\left(1+a_{n}\right)\text{ converges, for real }a_{n}>0}$$

Then it immediately follows that

$$\boxed{\sum|a_{n}|\text{ converges }\Leftrightarrow\prod(1+|a_{n}|)\text{ converges}}$$

because $|a_n|>0$, even for complex $a_n$ as required by the first criteria.

Question: This this logic correct? I am asking because I have seen source which derive the first criterion (eg), and then derive the second in a complicated way. What am I missing?
