As in [7] we consider classical system of interacting particles P_1, ... , P_n on the line with only neighboring particles involved in interaction. On the contrast to [7] now periodic boundary conditions are imposed onto the system, i.e. P_1 and P_n are considered neighboring. Periodic Toda...

We study classical multiparticle system (e.g. Toda lattice) on the line whose dynamics will be controlled by forces applied to few particles of the system. Various problem settings, typical for control theory are posed for this model; among those: studying accessibility and controllability...

We study controllability of 2D defocusing cubic Schroedinger equation under periodic boundary conditions and control applied via source term (additively). The source term is a linear combination of few complex exponentials (modes) with time-variant coefficients - controls. We manage to prove...

The authors investigate the strategic rationale behind the message sent by Osama bin Laden on the eve of the 2004 U.S. Presidential elections. They model this situation as a signaling game in which a population of receivers takes a binary choice, the outcome is decided by majority rule, sender...

I provide a simple example of a quadratic utility function that generates a Giffen demand. The utility function is symmetric, increasing and concave. Interestingly, the Giffen effect arises in the subspace where the utility function is strictly increasing and strictly concave. A full...

We analyze the career profiles of Italian legislators in the post-war period. Using a unique, newly collected dataset that contains detailed information on all the politicians who have been elected to the Italian Parliament between 1948 and 2008, we address a number of important issues that...

We consider a signalling game in which a population of receivers decide on the outcome by majority rule, sender and receivers have conflicting interests, and there is uncertainty about both players’ types. We model players rationality along the lines of recent findings in behavioral game...
