Denjoy's theorem on rotation number

In mathematics, the Denjoy theorem gives a sufficient condition for a diffeomorphism of the circle to be topologically conjugate to a diffeomorphism of a special kind, namely an irrational rotation. Denjoy proved the theorem in the course of his topological classification of homeomorphisms of the circle. He also gave an example of a C1 diffeomorphism with an irrational rotation number that is not conjugate to a rotation. (Wikipedia).

The Kurzweil Henstock Gauge Integral

In this video, I present an integral that is even better than Riemann and Lebesgue combined: Ladies and gentlement, I present you, the Gauge Integral, aka the Kurzweil or the Denjoy or the Henstock integral. This is an integral that allows more flexibility than the usual calculus integral,

Dividing two exponents with fractional powers

👉 Learn how to divide with rational powers. To divide with numbers/expressions with rational exponents, we apply the basic rules of exponents. If the two numbers/expressions are the same, we simply take one of the number and raise it to the power of the difference between the exponents of
