The geometry of

continued fractions

Anton Lukyanenko

It turns out that any real number can be written as a continued fraction:

x = a0 +1

a1 +1

a2+···.

We’ll see how working with continued fractions leads to thinking about hy-perbolic geometry, and then talk about generalizations to complex continuedfractions and Heisenberg continued fractions - and the related hyperbolicspaces. Lots of pictures, videos, and 3D prints will guide our intuition forthe geometries we encounter along the way.

The geometry of

continued fractions

Anton Lukyanenko

It turns out that any real number can be written as a contin-ued fraction:

x = a0 +1

a1 +1

a2+···.

We’ll see how working with continued fractions leads to think-ing about hyperbolic geometry, and then talk about general-izations to complex continued fractions and Heisenberg con-tinued fractions - and the related hyperbolic spaces. Lots ofpictures, videos, and 3D prints will guide our intuition for thegeometries we encounter along the way.
