Lei Liu completed her Master’s degree with the project title Complexity of Options in 2017.
An extension to monotone options (pictured) was presented at
ALH-2018. The new paper is called The number of languages with maximum state complexity and has been accepted for TAMC 2019.
As of 2022, the paper has been through 7 revisions and has been accepted for publication in the journal Algebra Universalis.

The undergraduate course MATH 454 (Axiomatic Set Theory) was taught in Fall 2021. Textbook: Schimmerling’s “A course on set theory”
A similar course at the graduate level was MATH 654 Fall 2020, which had the following readings:
- Foundations of Mathematics, Kenneth Kunen, parts of chapters I-IV.
- Modal logic for open minds, Johan van Benthem, some of chapters 1-11 and 16.
- Logic and Proof, Lean tutorial, and The Natural Number Game
Math 654 in Fall 2022 will use the textbook by Ebbinghaus, Flum, and Thomas and some readings about Lean.
