### Primitive Recursive Proof Systems for Arithmetic

#### David M. Cerna

RISC. Technical report, January 2018. In revision. [pdf]@

author = {David M. Cerna},

title = {{Primitive Recursive Proof Systems for Arithmetic}},

language = {english},

abstract = {Peano arithmetic, as formalized by Gentzen, can be presented as an axiom extensionof the LK-calculus with equality and an additional inference rule formalizing induction.While this formalism was enough (with the addition of some meta-theoretic argumentation)to show the consistency of arithmetic, alternative formulations of induction such asthe infinitary ω-rule and cyclic reasoning provide insight into the structure of arithmeticproofs obfuscated by the inference rule formulation of induction. For example, questionsconcerning the elimination of cut, consistency, and proof shape are given more clarity. Thesame could be said for functional interpretations of arithmetic such as system T whichenumerates the recursive functions provably total by arithmetic. A key feature of thesevariations on the formalization of arithmetic is that they get somewhat closer to formalizingthe concept of induction directly using the inferences of the LK-calculus, albeit byadding extra machinery at the meta-level. In this work we present a recursive sequentcalculus for arithmetic which can be syntactically translated into Gentzen formalism ofarithmetic and allows proof normalization to the LK-calculus with equality.},

### A General Recursive Construction for Schematic Resolution Derivations

#### David M. Cerna

2018. submitted for review. Preprint. [pdf]@

author = {David M. Cerna},

title = {{A General Recursive Construction for Schematic Resolution Derivations}},

language = {english},

abstract = {Proof schemata provide an alternative formalism for handling inductive argumentation, while non-trivially extending {\em Herbrand's theorem} to a fragment of arithmetic and thus allowing the construction of {\em Herbrand sequents} and {\em expansion trees}. Existing proof analysis methods for proof schemata extract an unsatisfiable characteristic formula representing the cut structure of the proof and from its refutation construct a Herbrand sequent. Unfortunately, constructing the refutation is a task which is highly non-trivial. An automated method for constructing such refutations exists, but it only works for a very weak fragment of arithmetic and is hard to use interactively. More expressive yet interactive methods for the formalization of recursive resolution refutation are complex, hard to work with, and still limited to an undesirably weak class of recursion. In this work we note a particular problem with previous methods, namely they mix the recursive structure with the calculus of refutation. Also we present a modular recursive structure independent of the resolution formalism and proof construction. We illustrate the expressive power of the so called {\em finite saturated tree} formalism by formalizing the Non-injectivity Assertion's schematic refutation (a variant of the infinitary Pigeonhole principle). None of the previously developed formalism are able to formalize this refutation.},

The mostcommonly used calculi contain a separate rule or axiom which reduces the important proof theoretic properties of the calculus. In such cases cut-elimination does not result in analytic proofs, i.e.\ every formula occurring in the proof is a subformula of the end sequent. Proof schemata are a generalization of \textbf{LK}-proofs able to simulate induction by linking proofs, indexed by a natural number, together.Using a global cut-elimination method a normal form can be reached which allows a schema of {\em Herbrand Sequents} to be produced, an essential step for proof analysis in the presence ofinduction. However, proof schema have only been studied in a limited context and are currentlydefined for a very particular proof structure based on a slight extension of the \textbf{LK}-calculus. The result is an opaque and complex formalization. In this paper, we introduce a calculus integrating the proof schema formalization and in the process we elucidate properties of proof schemata which can be used to extend the formalism. },
