This monograph grew out of the notes relating to the lecture courses that I gave at the University of Helsinki from 1977 to 1979, at the Eidgenossische Technische Hochschule Zurich in 1980, and at the University of Minnesota in 1982. The book presumably would never have been written without Fred Gehring's continuous encouragement. Thanks to the arrangements made by Edgar Reich and David Storvick, I was able to spend the fall term of 1982 in Minneapolis and do a good part of the writing there. Back in Finland, other commitments delayed the completion of the text. At the final stages of preparing the manuscript, I was assisted first by Mika Seppala and then by Jouni Luukkainen, who both had a grant from the Academy of Finland. I am greatly indebted to them for the improvements they made in the text. I also received valuable advice and criticism from Kari Astala, Richard Fehlmann, Barbara Flinn, Fred Gehring, Pentti Jarvi, Irwin Kra, Matti Lehtinen, I1ppo Louhivaara, Bruce Palka, Kurt Strebel, Kalevi Suominen, Pekka Tukia and Kalle Virtanen. To all of them I would like to express my gratitude. Raili Pauninsalo deserves special thanks for her patience and great care in typing the manuscript. Finally, I thank the editors for accepting my text in SpringerVerlag's well known series. Helsinki, Finland June 1986 Olli Lehto Contents Preface. ... ... ... ... ... ... ... ... ... v Introduction

Complex analysis, Joensuu 1978 : proceedings of the Colloquium on Complex Analysis, Joensuu, Finland, August 2427, 1978 by
Ilpo Laine(
Book
)
25 editions published between 1979 and 2008 in 3 languages and held by 404 WorldCat member libraries worldwide
The articles in this volume are for the most part research articles related mainly to the theory of quasiconformal and quasiregular mappings, Riemann surfaces and potential theory. They have resulted from talks delivered at the 13th Nevanlinna Colloquium, which was also a celebration of the 80th birthday of Lars V. Ahlfors: hence many articles in this volume reflect his mathematical interests

Mathematics without borders : a history of the International Mathematical Union by
Olli Lehto(
Book
)
16 editions published between 1998 and 2012 in English and held by 276 WorldCat member libraries worldwide
The history of international mathematical cooperation over the last hundred years  from the first international congress in 1897 to plans for the World Mathematical Year 2000  is a surprisingly compelling story. For reflected in the history of the International Mathematical Union (IMU) is all the strife among world powers, as well as aspirations for cooperation among nations in an increasingly interdependent world. As early as the 1920s, the IMU embraced principles of political neutrality, inviting every national mathematical organisation to join, and this principle of nondiscrimination, while sometimes sorely tried, has held the IMU in good stead. A number of issues  the Cold War, the conflict between the Peoples Republic of China and Taiwan, a divided Germany, problems in the emerging nations of Africa  at times led to attempts to influence the IMU Executive Committee in its decisions regarding membership, location of international congresses, committee assignments, handling of protests, and awarding the coveted Fields Medals. Yet throughout, the IMU has sponsored international congresses around the world, and Professor Lehtos gripping story is one of individuals, among them many of the great mathematicians of our century, united in the common purpose of advancing their science, told against the backdrop of world events

Proceedings of the International Congress of Mathematicians : August 311, 1994, Zürich, Switzerland by
International Congress of Mathematicians(
Book
)
23 editions published in 1980 in 3 languages and held by 188 WorldCat member libraries worldwide
Since the first ICM was held in Zürich in 1897, it has become the pinnacle of mathematical gatherings. It aims at giving an overview of the current state of different branches of mathematics and its applications as well as an insight into the treatment of special problems of exceptional importance. The proceedings of the ICMs have provided a rich chronology of mathematical development in all its branches and a unique documentation of contemporary research. They form an indispensable part of every mathematical library. The Proceedings of the International Congress of Mathematicians 1994, held in Zürich from August 3rd to 11th, 1994, are published in two volumes. Volume I contains an account of the organization of the Congress, the list of ordinary members, the reports on the work of the Fields Medalists and the Nevanlinna Prize Winner, the plenary onehour addresses, and the invited addresses presented at Section Meetings 1  6. Volume II contains the invited address for Section Meetings 7  19. A complete author index is included in both volumes. ' ... the content of these impressive two volumes sheds a certain light on the present state of mathematical sciences and anybody doing research in mathematics should look carefully at these Proceedings. For young people beginning research, this is even more important, so these are a must for any serious mathematics library. The graphical presentation is, as always with Birkhäuser, excellent ...

9 editions published in 2008 in German and held by 110 WorldCat member libraries worldwide
Rolf Nevanlinna (18951980) war ein weltberA1/4hmter Mathematiker, eine umstrittene politische Gestalt, eine AutoritAt auf dem Gebiet der Kultur und eine charismatische PersAnlichkeit. In allen Phasen seines Lebens waren die Mathematik und die Musik seine Leitsterne. a žMan muss sein Leben der Arbeit widmen und nach den erhabenen Welten streben" war sein Motto. Durch die Entwicklung der spAter nach ihm benannten NevanlinnaTheorie erlangte er in den 1920er Jahren Weltruf. Er wurde zum Professor der UniversitAt ZA1/4rich berufen und zum PrAsidenten der Internationalen Mathematischen Union
