GAMES AND NETWORKS

Marco Scarsini

Obiettivi formativi

The goal of the course is to expose the students to the basic concepts of strategic interactions, with a particular attention to situations that involve networks. The course will be mathematically formalized and rigorous.

Prerequisiti

Calculus, Multivariate Calculus, Linear Algebra, Elementary Probability

Risultati di apprendimento attesi

At the end of this course the student will understand some fundamental concepts of game theory and network theory, and will be able to 1. formally model some real-life situations in terms of games and on networks, 2. find the suitable solution concepts, 3. draw conclusions from the above modeling.

Contenuti Del Corso

The course will cover the basic aspects of non-cooperative game theory, i.e., games in normal form, mixed strategies, and main solution concepts (iterated elimination of dominated strategies, Nash equilibrium, correlated equilibrium), games in extensive form, behavior strategies, and main solution concepts (subgame perfect equilibrium), games with incomplete information. It will then move to network theory, starting with a survey of the basic concepts in graph theory and then moving to network formation (stochastic and strategic).
