\centerline{\bf Modes, modals, related  structures, and their applications}
\vskip1cm
We would like to inform you that the working meeting "Modes, modals, related
structures, and their applications" will take place in the Stefan Banach
International Mathematical Center in Warsaw, Poland, from March 9 until March
23, 1997. The meeting is intended to highlight recent developments in the
theory of modes (idempotent and entropic algebras) and modals
(semilattice-ordered modes), and interactions with other parts of algebra,
geometry, combinatorics and other disciplines. The aim of the meeting is to
bring together researchers working in these areas, and provide a forum for 
participants to meet, to share with others their recent results, and to work
together on unsolved problems in an informal atmosphere.
\medskip
The organizing committee consists of:
\medskip
\item{1.}J. Je\v zek, Praha, Czech Republic

\item{2.}K. Kearnes, Fayetteville, Arkansas, USA

\item{3.}A. Romanowska, Warsaw, Poland (co-chair)

\item{4.}J.D.H. Smith, Ames, Iowa, USA (co-chair) 

\item{5.}A. Szendrei, Szeged, Hungary

\medskip
Topics we expect to be considered include the following:
\medskip

\item{1.}Algebraic aspects of modes (structure, classification,
(quasi-)varieties, idempotent and entropic clones, representations)

\item{2.}Modals (modals of submodes, semilattice modes, semimodules and semirings)

\item{3.}Categorical aspects of modes and modals

\item{4.}Applications and relations to other areas:

\itemitem{(a)}rings and modules

\itemitem{(b)}geometry (affine, convex, differential)

\itemitem{(c)}combinatorics (codes, quasigroups, quandles)

\itemitem{(d)}functional analysis

\itemitem{(e)}algebraic topology (homotopy theory, knots), and possibly also
applications in computer science, physics and biology
\medskip
We expect about 20 (but no more than 30) participants. The schedule will
consist of 2 or 3 general talks in the mornings, and afternoon seminars.
Since the participants will come from different areas of mathematics, the
main talks should be prepared in such a way that non-specialists will be able
to follow and learn from them. Afternoon seminars can be more specialized.
The Banach Center strongly encourages research done during this type of
meeting, and expects publication of results.
