**Let be a Banach Space**

Open any mathematical journal and read the first sentence of a paper chosen at random. You will probably find something along the following lines: **“Let X be a Banach space”.** That is fine if you know what a Banach space is, but meaningless if you don’t.

Picking a recent issue of the *Bulletin of the American Mathematical Society* from the shelf, I chose a few papers at random. The titles and opening sentences were as follows:

*Arithmetic Hyperbolic Reflection Groups*: Consider a finite volume polyhedron in the -dimensional hyperbolic space .*Three Themes of Syzygies*: Free resolutions are both central objects and fruitful tools in commutative algebra.*An Overview of Periodic Elliptic Operators*: Elliptic PDEs with periodic coefficients, notably the stationary Schrödinger operator with a periodic potential , have been intensively studied.

Does anything here enlighten you in any way? Probably not. In reality, even professional mathematicians have great difficulty in understanding advanced mathematics in areas other than their own specialities and interests.

Of course, there is a great difficulty in explaining in simple terms the significance and content of a paper on advanced mathematics. For example, to elucidate the Banach space paper, one might begin by explaining that a Banach space is a complete, normed linear space. But that would immediately beg three questions:

- What does
*complete*mean? - What is a
*norm*? - What is a
*linear space*?

The answers would involve further excursions into analysis and algebra, requiring more layers of explanation.

** Baffling the Boffins **

**Mathgen** is a program to randomly generate professional-looking mathematics papers, including theorems, proofs, equations, discussion, and references. The automatic generation process succeeds because of the limited and formalised language used in most mathematical papers. The **Mathgen** program uses only a handful of sentence templates, and yet it is capable of producing documents that are remarkably close to those found in mathematical journals.

Many mathematical publications use stilted writing styles and contain numerous stock phrases. **Mathgen** constructs papers starting from a basic template and replaces blanks by various textual elements. These in turn contain blanks, so the construction is recursive.

Randomly-generated mathematics books have also been produced by **MathGen**. A recent example is *Galois Knot Theory: With Applications to Elementary Global K-Theory*, by J. Maruyama. URL

** MathGen papers accepted for publication**

Stefan Friedl of the University of Cologne had a **Mathgen** paper accepted by the Journal of Algebra and Number Theory Academia. It was entitled *On the uniqueness of prime, Jacobi functors*. The anonymous referees report offered unqualified praise for the paper:

“I have gone through the paper. It is a good paper. In my view the results obtained are original, new and interesting. This paper may trigger further research in the direction of work. Recommendation: I recommend that this paper be accepted for publication in the Journal.”

Unsurprisingly, the journal requires that the author pay an article processing charge of US$20 per page.

**Mathgen** was written by Nate Eldredge, Associate Professor at the University of Northern Colorado. His blog has a name reminiscent of the one you are reading now: \url{https://thatsmathematics.com}.

** Sample Papers generated using MathGen **

To bulk out my CV, I decided to generate a few publications using **Mathgen**. Below are five papers “written” by me in collaboration with some very big names in mathematics. The authors, title and opening sentence of each paper are given. At a casual glance, the papers — each produced in under a second — look realistic. But, of course, they are all complete rubbish. * Caveat lector.*
