*Prof. Dr. Maxim Kontsevich (Institut des Hautes Études Scientifiques):*

*“Introduction to tropical mathematics”*

**

/Abstract:/

I will introduce basic notions of tropical algebra and geometry. A tropical

semiring is endowed with operations of addition and multiplication (no

subtraction!) satisfying the usual rules of associativity, commutativity and

distributivity, plus the property saying that the addition is idempotent.

The main example of a tropical semiring is the set of real numbers with the

addition given by the maximum, and the multiplication given by the usual

sum. There are tropical analogs of algebraic subvarieties of a coordinate

space. These tropical varieties are piecewise-linear closed subsets of the

euclidean space. Many analogs of classical results from algebraic geometry

hold in the tropical setting.

I will explain the relation between tropical geometry and algebraic geometry

over nonarchimedean fields.

Also I'll speak about applications of tropical geometry to Mirror Symmetry,

and to potential counterexamples to the Hodge conjecture**

*Außerordentliches Mathematisches Kolloquium *

*Univ.-Prof. Dr. R. Tyrrell Rockafellar **(University of Washington,

*“*Stochastic Variational Inequalities: Singlestage to Multistage”*

**

/Abstracts:/

/Variational inequality modeling, analysis and computations are 
important for many/

/applications, but most of the subject has been developed in a 
deterministic setting/

/with no uncertainty in a problem's data. In recent years research has 
proceeded on a/

/track to incorporate stochasticity in one way or another. However, the 
main focus/

/has been on a rather limited idea of what a stochastic variational 
inequality might/

/be./

/Because variational inequalities are especially tuned to capturing 
conditions for/

/optimality and equilibrium, stochastic variational inequalities ought 
to provide such/

/service for problems of optimization and equilibrium in a stochastic 
setting./

/Therefore they ought to be able to deal with multistage decision 
processes involving/

/actions that respond to increasing levels of information, which has so 
far hadrly/

/been the case. This can be accommodated by bringing in the tools of/

/nonanticipativity and its martingale dualization, as will be explained./
