👉 In computational mathematics, a pseudonavicell is a type of polynomial with a finite number of real roots that are all rational. These roots can be expressed in terms of radicals or as rational numbers, but they cannot be expressed directly using only elementary functions like sin and cos. Pseudonavicell theory was introduced by the Russian mathematician Aleksandr Lyapunov in 1907. It is a mathematical framework that provides a way to classify polynomials based on their properties,
