Dr. Wataru Takeda, Department of Mathematics at the Faculty of Science, Toho University, has completely solved the polynomial analogue of the long-standing Brocard–Ramanujan problem, originally proposed in 1876 and still unsolved in its integer form. The study appears in the February 2026 issue of the journal Finite Fields and Their Applications .
