**An introduction to impredicative ordinal notation systems**

**DAVID FERNÁNDEZ-DUQUE**

UNIVERSITÉ PAUL SABATIER (Toulouse)

First session: November 2 (Wednesday), 6pm - 7:30pm, room 6.2.33

Second session: November 3 (Thursday), 3:30pm - 5pm, room 6.2.33

In this course we will give an introduction to ordinal notation systems based on collapsing cardinals in the style of Buchholz. Although familiarity with proof-theoretic ordinals is assumed, the course will work gradually, beginning with a quick review of predicative notation systems and introducing some intermediate systems along the way. The course will be divided in two sessions. Session 1: We introduce a general notion of ordinal notation system and show how the usual presentations for $\varepsilon_0$ and $\Gamma_0$ fall into this framework. We discuss the behavior of an uncountable ordinal within a notation system and introduce collapsing functions, culminating in a notation system for the Bachmann-Howard ordinal $\psi(\varepsilon_{\Omega+1})$. Session 2: We establish some important properties of $\psi(\varepsilon_{\Omega+1})$, including its computability. We motivate the role of multiple cardinals by considering collapsing functions with two uncountable cardinals. We then show how these techniques are extended to collapsing infinitely many cardinals. Time permitting, we discuss how larger sets (e.g., an inaccessible) can be used to construct even larger proof-theoretic ordinals.

**H-mesures and variants**

A short course by Nenad Antonic, April 18-21-22, 15:00-17:00.

Weak convergences are the foundations of most successful methods in the investigation of partial differential equations today. The approach known as <em>Tartar's programme</em> [15] proved particularly convenient for partial differential equations modelling physical laws; the basic assumption being that weak convergences of sequences of solutions model the transition from microscale to macroscale. We are particularly interested in mathematical objects being, in a generalised sense, accumulation points of weakly convergent sequences, such as defect measures or H-measures. H-measures are a microlocal analysis tool which has successfully been applied in a variety of applied analysis problems: in small amplitude homogenisation [16], in the theory of microstructure (problems with two or more potential wells) [10], in the study of propagation of oscillations and microlocal energy [17, 1], in controllability of partial differential equations [8], etc. The original H-measures are suited for the treatment of hyperbolic problems. Recently, different variants of the concept have been introduced, first allowing extension of the results to parabolic type problems [3, 5, 14], and later to problems of more general type.

Another successful application of H-measures is in the velocity averaging theory, as they enable generalisation of results obtained for constant coefficients (the homogeneous setting) to variable ones (the heterogeneous setting). First results of this kind are found in [9] for hyperbolic problems, while recent development of variant H-measures enabled generalisations to problems of various types [12], including other linear and even fractional differential equations. The notion of H-measures is given in the L2 framework, and the above results are constrained to solutions bounded in Lp, p>=2. By developping and applying appropriate tools, namely H-distributions [6], applications outside the L2 framework are also possible. Quite often, the nature of the problem requires a particular variant to be developed, prompting further research in constructing new objects.
