# An Algebraic Treatment of Recursion

## TL;DR

This paper reviews the main methods for defining recursion in process algebra and extends the algebraic approach to handle unguarded recursion, providing a comprehensive algebraic framework.

## Contribution

It introduces an extension of the algebraic method to accommodate unguarded recursion in process algebra.

## Key findings

- Extended algebraic approach to unguarded recursion
- Unified view of denotational, operational, and algebraic methods
- Enhanced algebraic framework for recursion

## Abstract

I review the three principal methods to assign meaning to recursion in process algebra: the denotational, the operational and the algebraic approach, and I extend the latter to unguarded recursion.
