Math & Physics Notes

Welcome to my collection of math and physics notes. This section is a work in progress, where I upload insights, research, and notes from my various projects. While primarily for my own use, I hope they may also be useful to others. I plan to expand this section and develop it more in the future.

Available Notes

Modern Differential Geometry

These are some of my notes from my Modern Geometry course in university. They cover some of the basics of differential geometry, and were taken from a combination of lectures and textbooks.

Combinatorics

These are two interesting research projects I worked on a few years ago with Greg Dresden involving visual interpretations of integer sequences.

Tiling a 2 x n Board with Dominos and L-Shaped Trominos

We count the number of ways to tile 2 x n rectangles and bracelets using dominos and L-shaped trominos. We show that these 2xn tilings can be related to 1xn tilings with squares, dominos, and two colors of k-minos for k ≥ 3, and we discover some new identities for old sequences.

Convolutions of Sequences with Similar Linear Recurrence Formulas

We show that a collection of convolution formulas involving the Fibonacci, Tribonacci, Pell, Jacobsthal, Narayana, and other number sequences can all be derived from a single elegant formula so long as the sequences follow certain mild requirements. We give many examples, both old and new.
