Written by eminent mathematicians from the international mathematical community, the chapters in this book are dedicated to the 60th birthday of Professor Helmut Maier. His own research has been groundbreaking and deeply influential, especially in the problem of gaps between consecutive primes. Helmut Maier was born in Geislingen/Steige, Germany, on October 17, 1953. He graduated with a Diploma in Mathematics from the University of Ulm in 1976, under the supervision of Professor H.E. Richert. After a period as a scientific employee at the University of Ulm, he started his doctoral studies at the University of Minnesota in 1979. He received his Ph.D. in 1981 with the thesis entitled Some results on prime numbers based on the application of sieve theory, under the supervision of Professor J. Ian Richards. The thesis was an extension of his paper Chains of large gaps between consecutive primes, which appeared in Advances in Mathematics, 39 (1981), 257–269. In this paper, Maier applied for the first time what is now called Maier’s Matrix Method. This method later on led him and other mathematicians to the discovery of unexpected irregularities in the distribution of prime numbers. The Matrix Method was also applied to other questions like irreducible polynomials and consecutive primes in the same residue class modulo an integer. After postdoctoral positions at the University of Michigan and the Institute for Advanced Study, Princeton, Maier then took a permanent position at the University of Georgia. During this period, he showed that the usual formulation of the Cramér model for the distribution of primes is wrong, a completely unexpected result. With C. Pomerance, he did research on the values of Euler’s '-function and large gaps between primes. One theme in this period was Professor Maier’s work on the size of the coefficients of cyclotomic polynomials, done partially in collaboration with S. Konyagin and E. Wirsing. He also collaborated with H.L. Montgomery on the size of the sum of the Möbius function under the assumption of the Riemann Hypothesis. Maier and G. Tenenbaum in joint work investigated the sequence of divisors of integers, solving the famous propinquity problem of Erdos.˝ v vi Preface Since 1993, Maier is a Professor at the University of Ulm, Germany. Lately, M.Th. Rassias and Maier worked on problems related to the Estermann zeta function and the Nyman–Beurling criterion on the Riemann Hypothesis involving the distribution of certain cotangent sums. In their latest work, they studied prime avoidance of perfect powers of prime numbers. Other collaborators of Professor Maier include P. Erdos,˝ J. Friedlander, A. Granville, D. Haase, A.J. Hildebrand, M.L. Lapidus, J.W. Neuberger, A. Sankaranarayanan, A. Sárközy, and C.L. Stewart. We are grateful to all of the mathematicians who participated in this publication. We also wish to express our thanks to Springer for undertaking the publication of this book. Hanover, NH, USA Carl Pomerance Princeton, NJ, USA Michael Th.

This generalizes a result of Kühne, who proved this for the line x1 C x2 D 1. 1 Introduction In this article with or without indices denotes a quadratic1 complex number with Im>0and j denotes the j-invariant. In 1998 André [1] proved that a non-special irreducible plane curve in C2 may have only finitely many CM-points. Here a plane curve is a curve defined by an irreducible polynomial equation F.x1; x2/ D 0, where F is a polynomial with 2 complex coefficients. A CM-point in C is a point of the form .j.1/; j.2// with quadratic 1;2. Special curves are the curves of the following types: 1“Quadratic” here and below means “of degree 2 over Q ”. B.
