The circle’s first pupil from India. His thesis, Distance and Transformation: A Study of Topological and Algebraic Structures, a work of one hundred and sixty-nine pages, proceeds from metric spaces and compactness, through groups, their actions and Sylow’s theorems, to linear maps, rings and fields. While still at school he showed, by a counterexample on three points, that an exercise in T. W. Körner’s A Companion to Analysis is false: the square of a metric need not be a metric. Tisya Chandrashekhar Rawat had found the gap in his first attempt at a proof, in the circle’s analysis seminar; Professor Körner, to whom he wrote, replied that his arguments were well founded. He qualified for the USA Mathematical Olympiad in 2025, and reads pure mathematics at Princeton.

Her thesis, Proofs of Some Classical Theorems Using Group Theory, drew a letter of particular appreciation from the admissions office at Caltech. She placed first in India in the Euclid Contest of 2023, with a place on its international honour roll, and won a gold medal in the Singapore and Asian Mathematics Olympiad. At Caltech she is preparing for research in geometric analysis and differential geometry.

A member of the national team of Cyprus at the International Mathematical Olympiad in 2021 and 2022, he received an honourable mention at the sixty-third Olympiad, at Oslo, for a complete solution to a problem in combinatorics. He was admitted also to Imperial College London, the University of Toronto and the University of St Andrews, and chose Chicago, to read mathematics.

She won a bronze medal at the European Girls’ Mathematical Olympiad in 2022. She was admitted also to Cornell University and the University of Wisconsin, and chose Toronto, to read mathematics and computer science.

Admitted as a pupil of marked ability and limited means, he wrote more than fifty pages of directed reading in analysis and group theory, and his original solutions were published in Mathematical Reflections and in Crux Mathematicorum, the journal of the Canadian Mathematical Society. He qualified for the American Invitational Mathematics Examination, and reads pure mathematics at KAIST.

His thesis, Symmetry and Structure: From Groups to the Fundamental Theorem of Galois Theory, of one hundred and eighty-three pages, grew from his directed study of graduate algebra. In the AMC 12A of 2025 he made the circle’s first perfect score, 150 of 150, and his original solutions have appeared in Mathematical Reflections and Crux Mathematicorum. He was admitted also to the University of Toronto and to the Hong Kong University of Science and Technology.
