Abstract

• We say that a sequence of functions {f n : D → ℝ} defined on a subset D ⊆ ℝ converges pointwise on D if for each xD the sequence of numbers {f n(x)} converge. If {f n} converges pointwise on D, then we define f : D → ℝ with \(f\left( x \right)\, = \,\mathop {\lim }\limits_{n \to \infty } \,f_n \left( x \right)\) for each xD. We denote this symbolically by f nf on D.
