I.M. Gelfand (1913 - 2009), one of the world's leading contemporary mathematicians, largely determined the modern view of functional analysis with its numerous relations to other branches of mathematics, including mathematical physics, algebra, topology, differential geometry and analysis. In this three-volume Collected Papers Gelfand presents a representative sample of his work. Gelfand's research led to the development of remarkable mathematical theories - most of which are now classics - in the field of Banach algebras, infinite-dimensional representations of Lie groups, the inverse Sturm-Liouville problem, cohomology of infinite-dimensional Lie algebras, integral geometry, generalized functions and general hypergeometric functions. The corresponding papers form the major part of the collection. Some articles on numerical methods and cybernetics as well as a few on biology are also included. A substantial number of the papers have been translated into English especially for this edition. The collection is rounded off by an extensive bibliography with almost 500 references. Gelfand's Collected Papers will be a great stimulus, especially for the younger generation, and will provide a strong incentive to researchers.

Serge Lang is not only one of the top mathematicians of our time, but also an excellent writer. He has made innumerable and invaluable contributions in diverse fields of mathematics and was honoured with the Cole Prize by the American Mathematical Society as well as with the Prix Carriere by the French Academy of Sciences. Here, 83 of his research papers are collected in four volumes, ranging over a variety of topics of interest to many readers.

Elsewhere 1 we were concerned with fundamental aspects of the question how man can comprehend his fellow-men. We analyzed man's subjective experiences of the Other and found in them the basis for his understanding of the Other's subjective processes of consciousness. The very assumption of the existence of the Other, however, introduces the dimension of intersub jectivity. The world is experienced by the Self as being inhabited by other Selves, as being a world for others and of others. As we had occasion to point out, intersubjective reality is by no means homogeneous. The social world in which man finds himself exhibits a complex structure; fellow-men appear to the Self under different aspects, to which correspond different cognitive styles by which the Self perceives and apprehends the Other's thoughts, motives, and actions. In the present investigation it will be our main task to describe the origin of the differentiated structures of social reality as well as to reveal the principles underlying its unity and coherence. It must be stressed that careful description of the processes which enable one man to understand another's thoughts and actions is a prerequisite for the methodology of the empirical social sciences. The question how a scientific interpretation of human action is possible can be resolved only if an adequate • From: De, sinnha/te A II/ball tler sowuen WeU, Vienna, 1932; 2nd ed. 1960 (Sektion IV: Strukturanalyse der Sozialwelt, Soziale Umwelt, Mitwelt, Vorwelt, English adaptation by Professor Thomas Luckmann.

R.S. Rivlin is one of the principal architects of nonlinear continuum mechanics: His work on the mechanics of rubber (in the 1940s and 50s) established the basis of finite elasticity theory. These volumes make most of his scientific papers available again and show the full scope and significance of his contributions.

Der vorliegende Band der "Gesammelten Aufsatze" tragt den Titel "Studien zur Phanomenologischen Philosophie." In ihm sind Alfred Schutz' Interpretationen phanomenologischer Haupt them en enthalten. An dieser Stelle soIl nun nicht die Interpreta tion noch einmal ausgelegt werden. Vielmehr wollen wir fragen, we1che Stellung der Autor in der sogenannten "Phanomenolo gischen Bewegung" einnimmt. Schutz selbst bestimmt in einer personlichen Tonbandaufzeich nung! seinen Standort in der Phanomenologie und seine Herkunft aus den philosophischen Schulen der Studienzeit. "Ich traf den groBen Denker zum erstenmal 1932, als er schon lange keine Vorlesungen mehr hielt, zwolf Jahre nach dem Ende meines Studiums an der Universitat Wien. Mein Weg zur Philo sophie Husserls war, wie er selbst einmal sagte, hochst ungewohn lich. Seit meinen fruhesten Studientagen galt mein Interesse am meisten der philosophischen Grundlegung der Sozialwissenschaf ten, besonders der Soziologie. Zu jener Zeit stand ich noch ganz im Banne Max Webers, insbesondere war ich von seinen methodo logischen Schriften fasziniert. Ich erkannte jedoch bald, daB Max Weber die Werkzeuge, we1che er fur seine konkrete Forschung benotigte, zwar geschmiedet hatte, daB aber sein Hauptproblem - das Verstehen des subjektiven Sinnes einer sozialen Handlung fur den Handelnden selbst - noch der philosophischen Begriin dung bedurfe. Mein Lehrer der Rechtsphilosophie, Hans Kelsen, hatte den Versuch unternommen, eine so1che philosophische 1 Tonbandaufzeichnung.
