In mathematics, specifically in real analysis, the Bolzano–Weierstrass theorem, named after Bernard Bolzano and Karl Weierstrass, is a fundamental result about convergence in a finite-dimensional Euclidean space $${\displaystyle \mathbb {R} ^{n}}$$.

WebBolzano-Weierstrass theorem, then we know for certain that the sequence has a convergent subsequence, even if we don’t know how to explicitly write that subsequence down. 4 / 12. Before we state the theorem, let’s first give a formal definition of subsequence of a sequence.
