From Sedbergh School to the London Mathematical Society: OS Egor Zaytsev’s (H 13-16) Mathematical Milestone

We are pleased to share news of OS Egor Zaytsev’s recent academic achievement, which marks an important step in his mathematical career.

Egor showed a strong interest and ability in mathematics during his time at Sedbergh, where he was encouraged to develop his skills. In 2015, he gained recognition in the UK Mathematics Trust Intermediate Challenge. These early experiences, supported by good teaching and encouragement, helped build the foundation for his later studies.

It is worth mentioning the guidance and mentorship from Dr A D P Worgan, (Chemistry Teacher), who played an important role during Egor’s school years and once said we would “hear Egor’s name again one day.”

That prediction has certainly proven true. On 31st March 2026, the Bulletin of the London Mathematical Society published Egor’s work on the Fractional Residue Theorem. In simple terms, his result offers a more direct way of evaluating certain complex integrals and adds a useful new perspective to a well-established area of mathematical analysis. Although Egor does not hold a maths degree (he did an integrated master’s in chemistry in the University of Manchester for 4 years, and then the PGCE in Oxford), he is currently a maths teacher and the paper published was based on the ideas he came up with while trying to come up with some more interesting problems for his highest attaining students.

It is rewarding to see how ideas first explored at school have developed into published research. Egor’s journey is a good example of how early curiosity, when supported, can grow into meaningful academic work at the highest level.

Congratulations to Egor on this impressive achievement. We look forward to seeing what comes next in his mathematical work.
