# Overview

The workshop is part of the Federated Logic Conference 2022 in Haifa, Israel, affiliated with the 25nd International Conference on Theory and Applications of Satisfiability Testing. There will be a joint session with the Workshop on Quantified Boolean Formulas and Beyond.

The topic of the workshop will be on proof complexity in a broad sense, and including proof complexity, bounded arithmetic, relations to SAT solving, relations to computational complexity, etc.

# Format

We plan to hold the workshop as an offline-only event.

# Scope

Proof complexity is the study of the complexity of theorem proving procedures. The central question in proof complexity is: given a theorem $F$ (e.g. a propositional tautology) and a proof system $P$ (i.e., a formalism usually comprised of axioms and rules), what is the size of the smallest proof of $F$ in the system $P$? Moreover, how difficult is it to construct a small proof? Many ingenious techniques have been developed to try to answer these questions, which bare tight relations to intricate theoretical open problems from computational complexity (such as the celebrated P vs. NP problem), mathematical logic (e.g. separating theories of Bounded Arithmetic) as well as to practical problems in SAT/QBF solving.

# Submission Guidelines

Abstracts are invited of ongoing, finished, or (if clearly stated) even recently published work on a topic relevant to the workshop.

The abstracts will appear in electronic pre-proceedings that will be distributed at the meeting.

Abstracts (at most 2 pages, in LNCS style; references do not count towards the limit) are to be submitted electronically in PDF via EasyChair
