Ted Hurley (born Thaddeus C. Hurley on 22nd 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. In 1976, Hurley was a founding member of the Irish Mathematical Society, and he served as its inaugural secretary (1977-1979).[1]

Early life and education

[edit]

Hurley was born and grew up in Tuam, Co. Galway, Ireland, to James Hurley and Bridget Walsh. He earned his BSc (1965) and MSc (1966) in mathematical science from University College Galway (UCG, now known at the University of Galway). There he won the Peel Prize in Geometry and the Sir Joseph Larmor Prize. 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. Gruenberg.[2]

Career

[edit]

After positions at Imperial College London, the University of Sheffield and University College Dublin (UCD), in 1980 Hurley took up a senior position at University College Galway (later known as the National University of Ireland Galway, and now as University of Galway. He was Statutory (Senior) Lecturer in Mathematics at UCG from 1980 to 1988, Associate Professor from 1988 to 1996, and Professor of Mathematics from 1996 on. He was Head of the Department of Mathematics from 1996 to 2001 and Head of Discipline from 2001 to 2010 within the School of Mathematics.

He has also been a vocal public commentator on mathematics' education, including the importance of numeracy and mathematics to our lives, in the Irish print media[1] and has also discussed these issues on popular national radio shows.

In 1976, Hurley was a founding member of the Irish Mathematical Society, and he served as its inaugural secretary (1977-1979).[3] Over the years, he has been a vocal public commentator on mathematics’ education—including the importance of numeracy and mathematics to our lives—in the Irish print media and radio.[4][1] Hurley’s work was originally mostly in group theory, specifically on structural features of infinite groups (relatively free groups, commutators and powers in groups), and also group rings. Later, his interests expanded to include algebraic coding theory and cryptography. 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. He showed that codes, including convolutional and quantum codes, could be constructed from known algebraic structures giving unique methods for constructing these to desired type, length, rate and distance,[10][11][12][13]. Cryptographic algebraic schemes (quantum safe) are described in [1],[14][2],[15] and methods for constructing non-separable matrices for use in information and quantum theory are described in [3].[16]
