• Listed under: ... >> Mathematics >> Mathematical Analysis
• Definition: Assume that we have f(x) = sum[(a_n)x^n] as n goes from 0 to infinity, and if -r < x < r. If the series also converges at x = r, then the limit as x -> r- of f(x) exists and we have lim f...

• Definition: The series sum[(a_n)(b_n)] converges if sum(a_n) converges and if {b_n} is a monotonic convergent sequence.
• #### Term: Accumulation Point

• Definition: If S is a subset of R^n and x is an element of R^n, then x is called an accumulation point of S if every n-ball B(x) contains at least one point of S distinct from x.

• Definition: Let S be a subset of R^n, and x a point in R^n, x not necessarily in S. Then x is said to be adherent to S if every n-ball B(x) contains at least one point of S.
• #### Term: Almost Everywhere

• Signs proposed: 0
• Listed under: ... >> Mathematics >> Mathematical Analysis
• Definition: A property is said to hold almost everywhere on a set S if it holds everywhere on S except for a set of measure 0.
• #### Term: Analytic Function

• Signs proposed: 0
• Listed under: ... >> Mathematics >> Mathematical Analysis
• Definition: Let f=u + iv be a complex-valued function defined on an open set S in the complex plane C. Then f is said to be analytic on S if the derivative f' exists and is continuous at every point of S.
• #### Term: Annulus

• Definition: The region lying between two concentric circles.
• #### Term: Approximation Property

• Signs proposed: 0
• Listed under: ... >> Mathematics >> Mathematical Analysis
• Definition: Let S be a nonempty set of real numbers with a supremum, say b = sup S. Then for ever a < b there is some x in S such that a < x <= b.
