# Symbolic Configurations and Two-Dimensional Mathematical Notation

## Abstract

In this paper a mathematical model is presented for defining the morphology and syntax of displayed mathematical expressions -- two-dimensional mathematical notation such as matrices, stacked fractions, and summation notation that are not usually written on a single line but displayed in text. A mathematical object, called a configuration, is used to model the spatial patterns or shapes in displayed mathematics. A rewriting system, called a configuration grammar, enables the description of the syntactic structure of displayed mathematics. Parsing procedures can be used with context-free configuration grammars and automatic character recognizers to interpret two-dimensional notations appearing in digitized images.
