The Oxford Murders

The fictional "Bormat's Last Theorem" solved in the film is a direct reference to Fermat's Last Theorem, a real mathematical problem widely regarded as one of the most challenging in history. Fermat's Last Theorem was proven in 1995 by Andrew Wiles Andrew Wiles, using elliptic curves, with the proof first presented at Cambridge University. This historical achievement mirrors the significance of solving Bormat's theorem in the film, emphasizing its impact on number theory.

The incorporation of Fermat's Last Theorem into the narrative was intentionally used to ground the film's mathematical themes in real-world academic history. The parallel between Bormat's and Fermat's theorems underscores the film's exploration of intellectual obsession and discovery.

During the classroom lecture at approximately 14 minutes, Martin states a belief in the number pi and characterizes it as the golden section, identifying it with the Fibonacci sequence. This statement constitutes a factual error, as the golden ratio signifies phi ($\phi$), while pi ($\pi$) represents the ratio of a circle's circumference to its diameter.

The background to the credits sequence is a representation of a blackboard full of equations and mathematical formulae.
