Budapest, Hungary; Data inizio: 2020-01-20; Note orario: 20-23 Jan. 2020; Riassunto: This is to inform students of the 8-hour course on the softwareSageMath, given by Prof. Peacute;ter Burcsi from Eouml;tvouml;s Loraacute;nd University, Budapest, Hungary, from 20 to 23 Jan. 2020. All students of all levels are welcome (PhD, master=magistrali, bachelor=triennalisti;computer science, mathematics, bioinformatics), as well as anyone else who is interested. Students are required to register for the course by sending an email to Laura Marcazzan, laura.marcazzan@univr.it. Short description: We give an overview and a brief introduction to the SAGE computer algebra system. SageMath (previously Sage or SAGE, System for Algebra and Geometry Experimentation) is a mathematical software with features covering many aspects of math, including algebra, combinatorics, numerical mathematics, number theory, calculus.

I will first introduce machine learning training and show that computational speedups directly translate into better ML models. I will then explain why design choices for ML systems are inevitably entangled with optimization and statistical considerations. Finally, I will provide two examples from my recent research activity: dynamic (TCP-like) adaptation of the number of ML workers, and topology design.

On one hand, we want to highlight how classical notions in combinatorics are applied to advance our understanding of biological/chemical processes. On the other hand, we want to show that such processes lead to new mathematical objects and drive new areas of research. We will give the biological background for DNA self-assembly and DNA recombination processes, as well as RNA structure formation. We will provide the combinatorial tools, mainly graph-theoretic approaches, to model and analyze such problems, and discuss some open questions related to these models.

After considering the simple case of a free rigid body, different types of examples will be covered before focusing on fluid dynamics. Eventually, the last lectures present a brief introduction to the application of these methods to the dynamics of nematic liquid crystals, in both ideal and dissipative cases.
