The existence of such a state, its optimality, its robustness against free bargaining among agents when there are many of them, its Wliqueness, its stability when price displacements evoke specified adjustments--all these issues have been studied, and continue to be studied in a variety of settings.

A tremendous amount of work has been done over the last thirty years in cluster analysis, with a significant amount occurring since 1960. The main intent of the monograph is to give the reader a quick account of the prob lem of cluster analysis and to expose to him the various aspects thereof.

In the course of one's research, the expediency of meeting contractual and other externally imposed deadlines too often seems to take priority over what may be more significant research findings in the longer run.

This work (in two parts), Lecture Notes in Economics and Mathe matical Systems, Volume 105 and 106, constitutes the Proceedings of the Fourteenth Biennual Seminar of the Canadian Mathematical Congress, which was held from August 12 to August 25, 1973 at the University of Western Ontario, London, Ontario.

On the conditions of optima1ity they deal mainly with generali- tions of known results to more general problems and also with less restrictive assumptions. This book is intended for researchers in nonlinear programming, and deals mainly with convex analysis, optimality conditions and duality in nonlinear programming.

The purpose of this book is to survey computational flow research on the design and analysis of supercritical wing sections supported by the National Aeronautics and Space Administration at the Energy Research and Development Administration Mathematics and Computing Laboratory of New York University.

Though the committee did not meet, per se, their inputs regarding format, possible participants, number of participants, length of the conference, and so on were of great value to me in planning and organizing the conference.

During the last fifteen years certain very fundamental aspects of economic theory have been very actively debated. In this debate certain important foundations of economic theory have been criticized which are specifically important for understand ing price formation and income distribution.

Certain comparative static properties of the maxima have proven to be of particular importance for economic theory, since the works of Slutsky, Hicks, and Samuelson [15]: they have been for- lated in terms of synunetry and negative semidefiniteness of a matrix, called the Slutsky-Hicks-Samuelson matrix.

I am also grateful to the late Professor Jacob Marschak and to Professor Arthur Geoffrion for sponsoring me as a Visiting Scholar of the Western Management Science Institute, Graduate School of Management, UCLA for the months of November and December 1977.

In reading the proceedings, it becomes apparent that bilinear systems, quadratic systems and more general variable structure or adaptive systems become natural models in many cases and excellent approximations in others.

It became apparent that identification of error-in-variables models was less of a problem when some dynamic features were present, and that the cathegory of "pre determined variables" was meaningless, since lagged endogenous and truly exogenous variables had very different identification properties.

The approach of ~ [1970, 1973, 1973a] has received most of the attention in the literature (Burmeister [1974], Faber [1975], Fehl [1975], ~[1975], Hagemann and ~ [1976]). The latter concept has been revived by the second group, to which Tintner [1970], von Weizs~cker [1971a, 1971b, 1974], ~ [1971, 1976 and ~ [1973, 1975, 1976] belong.

On February 20, 1978, the Department of Econometrics of the University of Tilburg organized a symposium on Convex Analysis and Mathematical th Economics to commemorate the 50 anniversary of the University.

They first pass through a server with service rate ~O' vari ance rate ~O' into a storage of finite capacity c . They then pass l through a server with service rate ~l' variance rate ~l' into a storage of capacity c ' etc., until finally, after passing through an nth server, 2 they go into an infinite reservoir (disappear).

The papers appearing in this Volume were selected from a collec tion of papers presented at the Internationa~ Symposium on Extrema~ Methods and Systems Ana~ysis on the Occasion of Professor A.

Reliability theory has become one of the important areas in Operational Research and Systems Engineering. A system deSigner is often faced with the problems of evaluation and improvement of system relia bility and determination of optimum preventive maintenance schedule.

He consider a cone dominance problem: given a "preference" cone lP and a set n X ~ R of available, or feasible, alternatives, the problem is to identify the non dominated elements of X.

The disjunctive cut principle of Balas and Jeroslow, and the related polyhedral annexation principle of Glover, provide new insights into cutting plane theory.

I was originally induced to think about barriers to entry by some re search done for Charles River Associates, Inc., Boston, on behalf of their client IBM Corporation, Armonk, N.Y.
