Convergence of Fourier Series Remark The theorem above is aboutpointwise convergenceof Fourier series. In classical harmonic analysis there are also theorems about other kinds of convergence of Fourier series, such as uniform convergenceor convergence in the mean. For these see, e.g., [Brown & Churchill, Pinsky].

Therefore, uniform convergence implies pointwise convergence. But the con-verse is false as we can see from the following counter-example. Example 10 Let {fn} be the sequence of functions on (0, ∞) deﬁned by fn(x) = nx 1+n2x2. This sequence converges pointwise to zero. Indeed, (1 + n2x2) ∼ n2x2 as n gets larger and larger. So, lim n→∞ ...

Lecture 2 : Convergence of a Sequence, Monotone sequences In less formal terms, a sequence is a set with an order in the sense that there is a rst element, second element and so on. In other words for each positive integer 1,2,3, ..., we associate an element in this set. In the sequel, we will consider only sequences of real numbers.

why Newton’s method converges so quickly (when it converges at all). Theorem 2. Let r be a xed-point of the iteration x n+1 = g(x n) and suppose that g0(r) = 0 but g00(r) 6= 0 . Then the iteration will have a quadratic rate of convergence. Proof. Using Taylor’s Theorem once again, but including one more term, we have g(x) = g(r) + g0(r)(x r ...
