Session 01
Title: Approximations of the best constants
Speaker: Prof. Liviu Ignat
Affiliation: Institute of Mathematics of the Romanian Academy
Abstract. In this talk we consider some well known quotients related with either eigenvalue problems, Sobolev or Hardy’s inequality. We consider the infimum of these quotients and their discrete analogous in a finite element subspace. We estimate the difference between the best constants above as the discretization parameter goes to zero and obtain sharp convergence rates.
Session 02
Title: Control and Machine Learning
Speaker: Prof. Enrique Zuazua
Affiliation: Head of DeustoCCM
Abstract. Systems control, or cybernetics—a term first coined by Ampère and later popularized by Norbert Wiener—refers to the science of control and communication in animals and machines. The pursuit of this field dates back to antiquity, driven by the desire to create machines that autonomously perform human tasks, thereby enhancing freedom and efficiency. The objectives of control systems closely parallel those of modern Artificial Intelligence (AI), illustrating both the profound unity within Mathematics and its extraordinary capacity to describe natural phenomena and drive technological innovation.
In this lecture, we will explore the connections between these mathematical disciplines and their broader implications. We will also discuss our recent work addressing two fundamental questions: Why does Machine Learning perform so effectively? And how can data-driven insights be integrated into the classical applied mathematics framework, particularly in the context of Partial Differential Equations (PDE) and numerical methods? This effort is leading us to a new emergening field of PDE+D(ata) in parallel to the development of new Digital Twins technologies.
