Dear Dynamic Game Theorist,
This is the twentythird issue of the Society's electronic newsletter.
The basic minimum work principle in editing this e-letter is that the
READERS send important notes and information about symposia, conferences
and workshops of dynamic games, as well as abstracts of Ph.D. theses,
papers and books, which they want to be included in the newsletter. The
format is described below. We hope that no retyping will be needed so
please follow the instructions and sample shown below carefully.
The news should be concise to keep the newsletter readable. Requests
for more complete information about any news item should be directed to
its contributor.
We appreciate any comments and suggestions that you may have on this
e-letter.
Looking forward to receiving your news contributions.
Raimo P. Hamalainen and Harri Ehtamo

MODEL FOR NEWS SUBMISSIONS
Maximum line length is 72 characters. Place the text between two
lines of x:ses. The first line should state "Contributed by" and
followed by the contributor's name, in brackets and
the date. Then there should be a title line and the text. This info
block should be sent to ISDG at HUT.FI

ISDG Joins the Web
ISDG now has a home page in the World Wide Web at
http://www.hut.fi/HUT/Systems.Analysis/isdg
Currently the pages contain a short description of the society, a list
of members, and copies of the past issues of ISDG News.
Let us know if you have a homepage of your own so we can link you to
the ISDG pages.
Have a look at the pages of Systems Analysis Laboratory, too:

A SEPARATION THEOREM FOR EXPECTED VALUE AND FEARED VALUE
DISCRETE TIME CONTROL
We show how the use of a parallel between the ordinary (+,x) and the
(max,+) algebras, Maslov measures that exploit this parallel, and more
specifically their specialization to probabilities and the
corresponding cost measures of Quadrat, offer a completely parallel
treatment of stochastic and minimax control of disturbed nonlinear
discrete time systems with partial information. This paper is based
upon, and improves, the discrete time part of the earlier paper
contributed to the St Jovite syposium of the ISDG, and published as P.
Bernhard: Expected Values, Feared Values and Optimal Control, in G-J.

DIFFERENTIAL PURSUIT GAMES ON THE SPHERE
Ph.D. dissertaton by Alexandr M. Kovshov
Supervizor: Leon A. Petrosjan
Ph.D. dissertation "Parallel pursuit strategies in the games on the
sphere" was defended by A. M. Kovshov in 25 june 1996 at the faculty
of Applied Mathematics of St.-Petersburg University. This work is
devoted to the consideration of pursuit strategies on the sphere.
These strategies are the variants of the well-studied "strategy of
parallel pursuit" for pursuit games on the plane, that has been
defined, investigated and described by L. A. Petrosjan. There are at
least two ways to transfer this strategy to the pursuit games on the
sphere. Each way produces a new strategy on the sphere and these
strategies are not the same. The first strategy conserves the bearing
of the pursuer relative to the evader. For example, if at some instant
the direction from the evader to the pursuer is a direction to the
north then the pursuer will be north of the evader till the end of the
game. The second strategy prescribes the pursuer to move along
geodesic lines. For example, if the evader moves along a geodesic
line all the time then the pursuer moves along another geodesic line
toward the intersection of these geodesic lines, such that both
players will reach the intersection point simultaneously. The
properties of both strategies are investigated. Two games on the
sphere are compared with the similar ones on the plane. These are the
"life-line" game and the simple-pursuit game without phase
restrictions.

GAME THEORETIC MODEL OF ATMOSPHERE PROTECTION
Ph.D. dissertation by Natalja I. Savischenko
Supervizor: Leon A. Petrosjan
The (N+1)-player game with one player A0 suffering from air pollution
and the rest of players indifferent to it is considered. The main
result consists construction of a (N+1)-player supergame defined on a
time interval [0,T]. The fixed partition of [0,T] to points 0 = Q0 <
... < Qn = T is given. At each time instant Qk the N indifferent
players decide between cooperative and noncooperative behavior with
A0, and as a result a subset Sk of cooperating players is formed at
each stage k of the supergame (under the assumption that once player i
decides noncooperation he can't cooperate at next stages of the
supergame). Then on the time interval [Qk, Qm), for m=k+1 of the
players from S_k the game proceedes as a cooperative differential
game, while the players from the remaining set N \ Sk playing Nash
strategies. For the cooperation a special time-consistent barganing
procedure is proposed. The strategies in supergame are described and
the set of Nash equilibria in supergame is found. The thesis
generalizes the approach first proposed in a Discussion Paper of L.
Petrosjan and G. Zaccour "A Multistage Game of Downstream Pollution".
