LadaTimotijevic: Developing responsible governance for an e-infrastructure: the case study of the Determinants and Intake “Richfields” Data Platform

11:00am, via Zoom

Big data provides immense opportunities to radically alter the way in which science is done, fostering cross-fertilisation between disciplines and providing connectivity between disparate data-sets. Distributed computing infrastructures – commonly known as e-infrastructures -have been created that provide researchers shared access to large data collections enabled through advanced ICT tools for data analysis, large-scale computing resources, and high-performance visualisation. However, the sheer scale of big data that poses ethical, legal and societal challenges to e-infrastructures. Using a case study as a practical example we explore how responsible governance is being forged in the context of the development of a public health e-infrastructure: Determinants and Intake (DI) “Richfields” Data Platform is an international e-infrastructure developed to connect data, services and tools for the study of human food related behaviour. The paper will pinpoint the shortages of the current legal framework in the EU applied to the governance of public health nutrition e-infrastructure

Luis Hernández-Lamoneda: Banach’s isometric problem

1:05pm, Zoom.

Let (V, ∥ · ∥) be a real Banach space. Fix n ≥ 2. Consider the following hypothesis:

Hn: all n-dimensional subspaces of V are isometric to each other.

In his 1932 book, Banach asked: Hn ⇒ (V, ∥ · ∥) is necessarily a Hilbert space?

This is the (real) “isometric problem of Banach”. It is easy to see -I’ll show it in the talk- that it really is a codimension 1 problem: if one knows that the question has a positive answer for a fixed n, for all (n + 1)-dimensional normed spaces, then it will have a positive answer, for that same n, for every (even infinite dimensional) Banach space (V, ∥ · ∥). Thus, one can restate Banach’s question as:

If all hyperplanes Γ ⊂ (R^{n+1}, ∥ · ∥) are isometric to each other, is (R^{n+1}, ∥ · ∥) euclidean (n+1)-space?

In 1967, Gromov showed that the answer is yes for even n. In proving it, he found a way to relate this problem to the existence of certain G-structures on S^n, thus allowing some of the machinery of algebraic topology to come to aid.

Recently (in joint work with G. Bor (CIMAT), V. Jiménez and L. Montejano (UNAM)) we have shown that Banach’s isometric problem has also a positive answer for every n ≡ 1 (mod 4), n ≠ 133.

In this talk I’ll give a sketch of the proof of this result. I’ll recall Gromov’s key idea mentioned above, which together with some algebraic topology theorems, plus some basic representation theory, translates the problem to one in convex geometry: namely, a certain characterization for (n+1)-dimensional ellipsoids.

Most of the arguments should be accessible to graduate students.
