Approximation Theory
Bernhard Riemann was a 19th-century German mathematician known for his contributions to various fields, including analysis, differential geometry, and number theory. His work laid the foundation for the Weierstrass Approximation Theorem, which states that any continuous function defined on a closed interval can be uniformly approximated by polynomials. This theorem highlights Riemann's influence on approximation theory and the deep connections between different areas of mathematics.
