Ted Hurley (born Thaddeus C. Hurley on 22 September 1944) is an Irish mathematician and retired university professor specialising in algebra, specifically in group theory, group rings, cryptography, coding theory and computer algebra.
He earned his PhD (1970) from the University of London for the thesis "Representations of Some Relatively Free Groups in Power Series Rings" done under Karl W.
In 1976, Hurley was a founding member of the Irish Mathematical Society, and he served as its inaugural secretary (1977-1979).
His main early works looked at existing problems and include: (i) critically improving Philip Hall’s famous work on Stability Groups,[5] (ii) providing the general solution to Fox’s problem on the identification of ideals in a group ring,[6] (iii) constructing counterexamples,[7] to the Lie Dimension subgroup conjecture which had been open for many years.
Work on group rings led,[6][8][9] to new results and structures in Coding Theory and in Cryptography.
