Littlewood, il teorema <strong>di</strong> <strong>di</strong>fferenziazione <strong>di</strong> Lebesgue, i teoremi <strong>di</strong> Morrey, <strong>di</strong> A.P. Calderòn, <strong>di</strong><br />

Rademacher-Stepanov, e <strong>di</strong>suguaglianze <strong>di</strong> tipo Poincaré, Sobolev e isoperimetriche.<br />

La parte geometrica è stata costituita da un'introduzione al bagaglio essenziale della geometria<br />

riemanniana, quali l'operatore <strong>di</strong> Laplace-Beltrami e il semigruppo del calore ad esso associato, il<br />

tensore <strong>di</strong> curvatura <strong>di</strong> Riemann, il tensore <strong>di</strong> Ricci, la teoria dei campi <strong>di</strong> Jacobi su cui poggiano i<br />

fondamentali risultati <strong>di</strong> confronto, quali il \comparison theorem" per l'operatore <strong>di</strong> Laplace-<br />

Beltrami e quello <strong>di</strong> Bishop-Gromov per il volume delle palle geodesiche.<br />

L'analisi e la geometria si sono poi coniugate nella parte del corso de<strong>di</strong>cata alla <strong>di</strong>mostrazione del<br />

“soap bubble theorem" <strong>di</strong> A. D. Alexandrov, al teorema <strong>di</strong> Bernstein sui grafici minimali, alla<br />

<strong>di</strong>suguaglianza <strong>di</strong> Harnack <strong>di</strong> Li-Yau per l'operatore del calore su una varietà avente tensore <strong>di</strong><br />

Ricci ≥ 0.<br />

RETI NEURONALI E INTELLIGENZA ARTIFICIALE<br />

(Prof. Alessandro Treves)<br />

Neural networks and the evolution of neural computation<br />

My course, in response to suggestions by SISSA student, will follow closely the presentation in<br />

Rolls and Treves, Neural Networks and Brain Function, Oxford UP, 1998, covering roughly one<br />

chapter or appen<strong>di</strong>x per meeting, with some extras. Students are advised to photocopy the whole<br />

book, and read the relevant chapters in advance of each meeting. After the meeting, they can read<br />

the ad<strong>di</strong>tional material or review the slides I will use and <strong>di</strong>stribute. The slides and all the material<br />

are in English, but if all the students in Padova speak Italian we can have the meetings in a flexible<br />

Italo-English.<br />

We should meet twice a week, for 11 weeks, with a schedule yet to be decided.<br />

The scheme to be followed per week will be<br />

Week 1: Introduction, and overview of research <strong>di</strong>rections in LIMBO, in one slide and loosely<br />

based on Ch. 1 of the book + App. 1 – Introduction to linear algebra<br />

Week 2: App. 2 (partial) – Elements of information theory + (no Chapter or Appen<strong>di</strong>x) – Geometry<br />

based computation: redundancy reduction à la Atick, from JJ Atick, ecological theory of sensory<br />

processing, Network 3:213 (1992).
