Given some random variables X_1, ... , X_n, one can form a vector of size 2^n-1 with the entropies of subsets of variables: [H(X_1), H(X_2), H(X_1,X_2), ... , H(X_1,...,X_n)]. The set of all possible such vectors is an object in the Euclidean space delimited by hyperplanes: information inequalities. Perhaps the most famous inequality is Shannon's basic inequality H(A,C) + H(B,C) = H(A) + H(A,B,C). We will see which role do these inequalities play in problems like secret sharing. I will also discuss a recent result on the geometry of inequalities based on duality of polymatroid.

Este año se vuelven a programar cursos en la R School (4 cursos) y en la Big Data School (3 cursos). Además hay otros 4 cursos de diferentes temas. En el link anterior podéis encontrar la descripción de cada curso y una reseña sobre el profesorado que impartirá cada uno de ellos.

La semana que viene (del 18 al 22 de abril) se abre el plazo de solicitud de plazas en estos cursos. La matrícula será del 9 al 13 de mayo.

Recordar que para los profesores del MESIO UPC-UB la matrícula en estos cursos es gratuita y que nos podemos apuntar a ellos, salvo en el caso de que un curso llegue a los 25 matriculados (sin contar profesores).

Os animamos a que examinéis la programación del Summer School 2016 y a que os inscribáis en los cursos que os interesen durante estos días de abril, porque eso nos permite tener garantía de que los cursos serán viables (los cursos con menos de 5 personas matriculadas no se llevarán a cabo).

# Description

Many natural mathematical concepts cannot be expressed in first-order logic but need stronger logics. Among such concepts are the freeness of a group, separability of a space, completeness of an order, etc. By a strong logic we mean model-theoretically defined extensions of first-order logic, such as first-order logic with generalized quantifiers, infinitary logics, second-order logic, as well as higher-order logics. The study of strong logics runs immediately into questions that depend essentially on set-theoretical assumptions beyond the standard ZFC axioms, such as infinitary combinatorial principles and the existence of large cardinals. It is therefore crucial to be able to pinpoint the position of a given strong logic in the set-theoretical definability hierarchy, thus helping us understand better the set-theoretical nature of the logic, and therefore of the mathematical notions it can express.

# Objectives

This program will bring to the CRM a diverse group of international high-level researchers working in strong logics, large cardinals, the foundations of set theory, and the applications of set-theoretical methods in other areas of mathematics, such as algebra, set-theoretical topology, category theory, algebraic topology, homotopy theory, C*-algebras, measure theory, etc. In all these areas there are not only direct set-theoretical applications but also new results and methods, which are amenable to the expressive power of strong logics.
During the Research Program the following activities will be held:
Advanced Course on Large Cardinals and Strong Logics, from September 19 to 23, 2016. Deadline for registration: August 1st, 2016. More information on registration and grants available at Link
Workshop 1: Set-theoretical aspects of the model theory of strong logics, from September 26 to 30, 2016. Deadline for registration: August 1st, 2016. More information on registration and grants available at Link
Young researcher’s Seminar week, from November 7 to 11, 2016. You can participate by presenting your work before October 31, 2016. More information on how to participate at Link
Workshop 2: Applications of strong logics in other areas of mathematics, from November 14 to 18, 2016. Deadline for registration: November 6, 2016. More information on registration and grants available at Link
