Abstract:
The Lagrange value of a real number measures how well it
can be approximated by rationals where the approximation is measured
in terms of denominator. Considered as a subset of the real line,
the set of all Lagrange values has a very interesting structure. This
talk will develop the approximation problem from
basic principles and progress to a natural generalization.
