Hiroshi Ohta – författare

A festschrift to honour Mel Greenhut, who has long toiled on spatial economics, this book focuses on a single question - if and how economic space matters, discussing theoretical, as well as historical issues of contemporary relevance. Subjects covered include historical accounts of spatial economics; land use and public goods; and location theory and spatial competition. Hiroshi Ohta is the author of "Theory of Spatial Pricing and Market Areas" (with M.L. Greenhut), "Spatial Price Theory of Imperfect Competition" and "New Frontiers in Regional Science". Jacques-Francois Thisse is the co-author of "Discrete Choice Theory of Product Differentiation". The contributors include Simon P. Anderson, William J. Baumol, Bruce L. Benson, Andre de Palma, B. Curtis Easton, Nicholas S. Economides, Robert B. Ekelund Jr, Ronald D. Fischer, John G. Greenhut, Timothy J. Gronberg, Robert E. Hebert, Hong Hwang, Amoz Kats, Tatsuhiko Kawashima, Chao-Cheng Mai, Milton H. Marquis, Edwin S. Mills, Gordon M. Myers, Hisao Nishioka, George Norman, Yorgos Y. Papageorgiou, Louis Phlips, Susan Rose-Ackerman, Noboru Sakashita, Paul A. Samuelson, Douglas G. Sauer, Thomas R.Saving, Nicolas Schmitt, Takaaki Takahashi, Michaus T. Tideman.

A co-publication of the AMS and International Press of Boston, Inc.This is a two-volume series research monograph on the general Lagrangian Floer theory and on the accompanying homological algebra of filtered A?A?-algebras. This book provides the most important step towards a rigorous foundation of the Fukaya category in general context. In Volume I, general deformation theory of the Floer cohomology is developed in both algebraic and geometric contexts. An essentially self-contained homotopy theory of filtered A?A? algebras and A?A? bimodules and applications of their obstruction-deformation theory to the Lagrangian Floer theory are presented. Volume II contains detailed studies of two of the main points of the foundation of the theory: transversality and orientation. The study of transversality is based on the virtual fundamental chain techniques (the theory of Kuranishi structures and their multisections) and chain level intersection theories. A detailed analysis comparing the orientations of the moduli spaces and their fiber products is carried out. A self-contained account of the general theory of Kuranishi structures is also included in the appendix of this volume.

In this book, leading scholars of international stature try to find ways of introducing space in economic theory which will make it simpler and more realistic, analysing theoretical and historical issues of contemporary relevance, such as land use, congestion and public goods, location theory and spatial competition.

The Memoirs of the AMS is devoted to the publication of new research in all areas of pure and applied mathematics. The Memoirs is designed particularly to publish long papers of groups of cognate papers in book form, and is under the supervision of the Editorial Committee of the AMS journal Transactions of the American Mathematical Society. All papers are peer-reviewed.

This handbook offers an exposition of the contemporary status of Japan's environmental law, policy, and politics. The compass of ecological quandaries explored within this tome is expansive, encompassing issues pertinent to both natural and synthetic ecosystems, natural resources, and inorganic materials.

Answering popular demand, the authors now present the current book, in which they provide a detailed, self-contained explanation of the theory of Kuranishi structures. Part I discusses the theory on a single space equipped with Kuranishi structure, called a K-space, and its relevant basic package.
