# Forms of Plagiarism in Digital Mathematical Libraries

## TL;DR

This paper explores various forms of plagiarism in mathematical publications, analyzing editorial notes from zbMATH to identify simple and disguised cases, and evaluates current detection systems' effectiveness.

## Contribution

It provides a detailed classification of plagiarism types in mathematical literature and assesses the capabilities of existing detection tools.

## Key findings

- Most plagiarism cases are simple copies
- Disguised plagiarism forms are also present
- Current detection systems have limitations

## Abstract

We report on an exploratory analysis of the forms of plagiarism observable in mathematical publications, which we identified by investigating editorial notes from zbMATH. While most cases we encountered were simple copies of earlier work, we also identified several forms of disguised plagiarism. We investigated 11 cases in detail and evaluate how current plagiarism detection systems perform in identifying these cases. Moreover, we describe the steps required to discover these and potentially undiscovered cases in the future.
