Share this page *Edited by *
*G. L. Litvinov; S. N. Sergeev*

This volume contains the proceedings of the International Workshop on
Tropical and Idempotent Mathematics, held at the Independent
University of Moscow, Russia, from August 26–31, 2012. The main
purpose of the conference was to bring together and unite researchers
and specialists in various areas of tropical and idempotent
mathematics and applications.

This volume contains articles on algebraic foundations of tropical
mathematics as well as articles on applications of tropical
mathematics in various fields as diverse as economics,
electroenergetic networks, chemical reactions, representation theory,
and foundations of classical thermodynamics.

This volume is intended for graduate students and researchers
interested in tropical and idempotent mathematics or in their
applications in other areas of mathematics and in technical
sciences.

#### Readership

Graduate students and research mathematicians interested in tropical and idempotent mathematics and its applications.
