Descriptive Mathematics and Computer Science with Polynomial Ordinary Differential Equations.
We will see that many continuous and discrete concepts from mathematics and computer science can be presented using ordinary differential equations. Basically, we will start from the following observation: if you know what 0, 1, -1 are, as well as what an addition and a multiplication are, and if you remember what an ordinary differential equation is, then you can define and program many concepts from Mathematics and Computer Science. In particular we will present/rediscover descriptive complexity, computability and complexity using polynomial ordinary differential equations only. A title for this talk could also be "Programming with Ordinary Differential Equations”, as these questions also relate to analog models of computations, and in particular to the 1941 General Purpose Analog Computer of Claude Shannon. In some way, we are rediscovering the forgotten art of their programming, and we are only starting to understand the true power of these very old models.

Holey Shapes with Trees and Cotrees
We prove that for every simplicial complex, K, and every dimension, p, there is a partition of the p-simplices into a maximal p-tree, a maximal p-cotree, and the remaining p-simplices defining the p-th homology of K. Given a monotonic order of the simplices, this tri-partition is unique and can be computed by standard matrix reduction. We use it as a data structure to facilitate the opening and closing of holes in subcomplexes of K. In concrete applications, we let K be the Delaunay triangulation of a finite set, and we enhance the persistence diagram of the Euclidean distance function with the tri-partition to guide the opening and closing of holes in its alpha subcomplexes. Joint work with Katharina Oelsboeck.

Computational Complexity and the Independence Polynomial
The independence polynomial is one of the most well-studied graph polynomials, arising in combinatorics and computer science. It is also known in statistical physics as the "partition function of the hard-core model". After describing the polynomial, I will tell you something about the complexity of approximating this polynomial, including the now-classical breakthrough results of Weitz and Sly, incursions into the complex plane by Harvey, Srivastava, and Vondr\'ak and by Patel and Regts and finally more recent work using tools from complex analysis by Peters and Regts and also in joint work with Bezakova, Galanis, and Stefankovic.

A computer scientist thinks about the Brain
How does the Brain give rise to the Mind? How do neurons and synapses, molecules and genes, ​​ evolution and development, give rise to behavior and cognition, language and intelligence? Despite lightning progress in recording and molecular technology and a deluge of experimental data, we do not seem to get closer to an answer. This is a talk about admiring and appreciating the problem, and proposing a new approach based on a recognized but little studied intermediate level of Brain computation carried out by the synchronous firing of large and highly interconnected sets of neurons called assemblies. We show that assemblies give rise to a novel computational system, and we speculate that they may instrument higher cognitive functions, such as language and math.
