Springer-Verlag began publishing books in higher mathematics in 1920,
when the series Grundlehren der mathematischen Wissenschaften,
initially conceived as a series of advanced textbooks, was founded by
Richard Courant. A few years later a new series Ergebnisse der
Mathematik und ihrer Grenzgebiete, survey reports of recent
mathematical research, was added.
Of over 400 books published in these series, many have become recognized
classics and remain standard references for their subject. Springer is
reissuing a selected few of these highly successful books in a new,
inexpensive sofcover edition to make them easily accessible to younger
generations of students and researchers.
