[parent] Weierstrass' criterion of uniform convergence (Theorem)
Theorem 1   Let the real functions $ f_1(x)$, $ f_2(x)$, ... be defined in the interval $ [a, b]$. If they all satisfy the condition
$\displaystyle \vert f_n(x)\vert \leqq M_n \quad \forall\,x\in[a, b],$
with $ \sum_{n = 1}^{\infty}M_n$ a convergent series of constant terms, then the function series
$\displaystyle f_1(x)\!+\!f_2(x)\!+\!\cdots$
converges uniformly on the interval $ [a, b]$.

The theorem is valid also for the series with complex function terms, when one replaces the interval with a subset of $ \mathbb{C}$.
