The number of languages with maximum state complexity

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.

Principles-based classification

I was the discussant for the following paper at Hawaii Accounting Research Conference 2020 on the UH Hilo campus:

The Contract Disclosure Mandate and Earnings Management under External Scrutiny

by Carlos Corona and Tae-Wook Ryan Kim

Discussant slides

I learned that research in the Theory Track of the accounting discipline primarily is about mathematical modeling of the effects of government policies and business decisions. It borrows methods from economics for such modeling. In the case of the Corona-Kim paper: quadratic programming without constraints, and exponential utility functions. Usually these are not empirical papers, i.e., they don’t test the model explicitly against data. Indeed this would be hard to do with notions like “intensity of scrutiny”.

I am a discussant for “A theory of principles-based classification” by Konvalinka, Penno, and Stecher, at HARC 2021.
