This is a list of articles that are considered real analysis topics.

General topics[edit]

Limits[edit]

Sequences and series[edit]

(see also list of mathematical series)

Summation methods[edit]

More advanced topics[edit]

  • Convolution
  • Farey sequence – the sequence of completely reduced fractions between 0 and 1
  • Oscillation – is the behaviour of a sequence of real numbers or a real-valued function, which does not converge, but also does not diverge to +∞ or −∞; and is also a quantitative measure for that.
  • Indeterminate forms – algebraic expressions gained in the context of limits. The indeterminate forms include 00, 0/0, 1, ∞ − ∞, ∞/∞, 0 × ∞, and ∞0.

Fundamental theorems[edit]

  • Monotone convergence theorem – relates monotonicity with convergence
  • Intermediate value theorem – states that for each value between the least upper bound and greatest lower bound of the image of a continuous function there is at least one point in its domain that the function maps to that value
  • Rolle's theorem – essentially states that a differentiable function which attains equal values at two distinct points must have a point somewhere between them where the first derivative is zero
  • Mean value theorem – that given an arc of a differentiable curve, there is at least one point on that arc at which the derivative of the curve is equal to the "average" derivative of the arc
  • Taylor's theorem – gives an approximation of a times differentiable function around a given point by a -th order Taylor-polynomial.
  • L'Hôpital's rule – uses derivatives to help evaluate limits involving indeterminate forms
  • Abel's theorem – relates the limit of a power series to the sum of its coefficients
  • Lagrange inversion theorem – gives the Taylor series of the inverse of an analytic function
  • Darboux's theorem – states that all functions that result from the differentiation of other functions have the intermediate value property: the image of an interval is also an interval
  • Heine–Borel theorem – sometimes used as the defining property of compactness
  • Bolzano–Weierstrass theorem – states that each bounded sequence in has a convergent subsequence.
  • Extreme value theorem - states that if a function is continuous in the closed and bounded interval , then it must attain a maximum and a minimum, each at least once.
