The author is a disciple of Paul Erdős, who taught him about Asymptopia. Primes less than , graphs with vertices, random walks of
steps--Erdős was fascinated by the limiting behavior as the variables
approached, but never reached, infinity. Asymptotics is very much an
art. The various functions , , , ,
all have distinct personalities. Erdős knew these functions as
personal friends. It is the author's hope that these insights may be
passed on, that the reader may similarly feel which function has the
right temperament for a given task. This book is aimed at strong
undergraduates, though it is also suitable for particularly good high
school students or for graduates wanting to learn some basic
techniques.
Asymptopia is a beautiful world. Enjoy!
