This Fall I will be a first year mathematics PhD student at UCLA. I enjoy doing analysis - particularly of the functional variety.

## Littlewood’s Three Principles (3/3)

So far we’ve proven Littlewood’s first and third principles. In this last installment, we’ll prove his second principle, that “every function is nearly continuous.” This result is better known as Lusin’s Theorem. Advertisements

## Littlewood’s Three Principles (2/3)

Littlewood’s three principles provide useful intuition for those first learning measure theory: “The extent of knowledge [of real analysis] required is nothing like as great as is sometimes supposed. There are three principles, roughly expressible in the following terms: Every … Continue reading

## Littlewood’s Three Principles (1/3)

When I first studied measure theory, I felt like I could never quite wrap my head around what a measurable set or function looked like. After all, the Borel Heirarchy is huge, and what the hell does a set look … Continue reading

## Happy Birthday, Hotovy!

On this day a few centuries ago, Whateversuitsyourboat’s very own ([Raspy] Ryan) Hotovy was born! Now, a few millennia later, Hotovy is engaged, pursuing his PhD in mathematics at Texas A&M, and presumably getting better at taking cross products! Happy … Continue reading

## A subtle problem.

Let be given by Here’s the problem: For all , does there exist some (dependent on ) for which ? (Of course, denotes iteration of , times.) If this is true, then notice the orbit of will always converge to the … Continue reading
