Impact. “Alf van der Poorten is known worldwide among number theorists
and those working in immediately related fields by virtue of his insightful simplifying observations, a variety of unexpected and interesting theorems, and theexcellence of his expository writings and lectures. His publications include joint
papers with a wide variety of other well known names in number theory.
Van der Poorten’s present work, motivated by methods of modern cryptography, computational number theory, and transcendence theory, includes a study
algebraic curves by way of their sequence of Padé approximants.
The special case, continued fraction convergents, is relevant to the hyperelliptic
case. That has already provided insights into matters as apparently diverse as
pseudo-elliptic integrals [amusing, and relevant to computer integration], families of hyperelliptic cuves of increasing genus g and with relatively high torsion
in terms of g [here it is ‘believed’ one can do no better than O(g 2 )], Somossequences [thus also elliptic divisibility sequences in the generic elliptic case],regulators of parametrised sequences of quadratic number fields of increasing
discriminant, . . . . ”

Some Research Highlights.
In the mid-seventies, Van der Poorten noticed that the disjoint sequences of refinements to Baker’s inequalities were after all readily unified. His first principles
approaches made the ‘difficulties’ in the p-adic case vanish forever. John Loxton
and he generalised ‘Mahler’s Method’ and established it as a major techniquein transcendence theory.
In 1978, his lively exposition of Apéry’s claims provided the only detailed
exposition of the proof. More recently, Alf van der Poorten’s book, Notes on
Fermat’s Last Theorem, an explanation of the basics underlying Wiles’ proof,
attracted warm critical support.
Van derPPoorten proved Pisot’s conjecture to thethat if the
P∞Hadamard
Peffect∞∞hhquotient h=0 (ch /bh )X of two rational functions h=0 ch X and h=0 bh X h ispossibly rational then in fact it is rational, using a new rationality criterion dual
to that employed in Dwork’s proof of the Weil conjectures. An application is acomplete proof of Morgan Ward’s question about recurrence sequences yielding
divisibility sequences.
In 1982 he remarked that by excluding vanishing subsums and by applying
specialisation principles developed in the course of studying the HQT, it followedthat there are only finitely many solutions to equations u1 + u2 + · · · + un = 1 inelements ui of a finitely generated group. This is the celebrated S-unit theorem.
Jointly with Bernie Dwork, van der Poorten studied the ‘Eisenstein constant’,
providing sharp bounds on the Taylor coefficients of an algebraic power series.
Kenneth Williams and he succeeded in breaking up the Chowla–Selberg formula, allowing evaluation of the Dedekind eta function for all discriminants interms of singular values of L-functions.
Alf van der Poorten has made himself a, probably the, expert in usefully
torturing continued fraction expansions, both of numbers and of formal power
series. He is not yet certain whether current work exploring continued fraction
expansion of square roots of generic polynomials is incisive or merely amusing.
Work, begun in the early eighties, led to Enrico Bombieri’s invariant ThueSiegel method and has been pursued by Van der Poorten in the form of explicit
construction of curves with prescribed singularities at (0, 0), (1, 1) and (∞, ∞).
