Well, of course not.
Marcie Rathke of the University of Southern North Dakota at Hoople submitted a manuscript to the peer-reviewed journal Advances in Pure Mathematics. It was a long string of fake mathematical reasoning created with a computer program:
The paper was created using Mathgen, an online random maths paper generator. Mathgen has a set of rules that define how papers are arranged in sections and what kinds of sentence make up a section and how those sentences are made up from different categories of technical and non-technical words. It createsbeautifully formatted papers with the conventional structure, complete with equations and citations but, alas, totally devoid of meaning.
Nonetheless, the editors of Advances in Pure Mathematics, after receiving favorable reports from reviewers, agreed to publish Rathke's manuscript.
