Surveys and Notes
A growing collection of my own surveys and notes, alongside recommendations of other writing I’ve found valuable. Entries marked Mine are my own.
Bounded Arithmetic
Bounded arithmetic (or feasible mathematics) corresponds to mathematical theories relying on concepts only from a complexity class, ranging from AC⁰, P, PSPACE, and even beyond.
Mine survey
Jiatu Li · ECCC TR25-086 · 2025
A gentle introduction to Cook’s theory PV targeting to computer scientists. Compared to existing textbooks, it features an informal definition of PV based on three postulates, which captures the high-level intuition, as well as a careful roadmap from axioms to formalizations of complicated mathematics.
survey
Igor Carboni Oliveira · ECCC TR25-041 · 2025
A recent comprehensive survey on unprovability results in bounded arithmetic.
textbook
Jan Krajíček · Cambridge University Press · 2019
The comprehensive reference for proof complexity and bounded arithmetic — a standard textbook to reach for when you want a full picture of the field.
Range Avoidance
The Range Avoidance problem asks for a string outside the range of a given stretching circuit, like finding water in the ocean. Apparently, it is not an easy task.
survey
Oliver Korten · Bulletin of the EATCS, No. 145 · 2025
An overview of this research direction and its connections to fundamental questions in derandomization and circuit complexity.
Catalytic Computation
Catalytic computing studies space-bounded computation that may borrow a large, full memory, provided its contents are restored by the end. How can it be useful?
survey
Ian Mertz · Bulletin of the EATCS · 2023
An accessible survey of catalytic computing, with a great collection of open problems.
