MCCCC — 34th Midwest Conference on Combinatorics and Combinatorial Computing
16 Oct 2020 - 18 Oct 2020 • Las Vegas, NV, United States
Organizer:
Hosted at the University of Nevada, Las Vegas
Abstract:
The Midwestern Conference on Combinatorics and Combinatorial Computing (MCCCC) originally started as the Carbondale Combinatorics Conferences and were held (1986-1990) at the Southern Illinois University, Carbondale. The conference has since evolved to a prestigious national conference in the areas of Combinatorics and Computing and has achieved recognition and attracted scholars and researchers of various backgrounds from different institutions. Here they coalesce their individual contributions into a collection of ideas and inspirations for the advancement of combinatorics and combinatorial computing.

Combinatorial Algebraic Geometry
01 Feb 2021 - 07 May 2021 • Providence, RI, United States
Organizer:
ICERM
Abstract:
Research in combinatorial algebraic geometry utilizes combinatorial techniques to answer questions about geometry. Typical examples include predictions about singularities, construction of degenerations, and computation of geometric invariants such as Gromov-Witten invariants, Euler characteristics, the number of points in intersections, multiplicities, genera, and many more. The study of positivity properties of geometric invariants is one of the driving forces behind the interplay between geometry and combinatorics. Flag manifolds and Schubert calculus are particularly rich sources of invariants with positivity properties.

Sage/Oscar Days for Combinatorial Algebraic Geometry
15 Feb 2021 - 19 Feb 2021 • Providence, RI, United States
Organizer:
ICERM
Abstract:
This workshop will focus on the development of software to facilitate research in combinatorial algebraic geometry, based on the SAGE Mathematical Software System and the OSCAR Computer Algebra System. Special attention will be given to efficient computations with multi-variate polynomials, which is a critical part of many algorithms in combinatorial algebraic geometry. Aside from development of software, the workshop will feature a series of talks about polynomial computations, as well as introductory lectures about Sage and Oscar.

Deep Learning and Combinatorial Optimization
22 Feb 2021 - 26 Feb 2021 • Los Angeles, CA, United States
Organizer:
Institute of Pure and Applied Mathematics (IPAM), UCLA
Abstract:
In recent years, deep learning has significantly improved the fields of computer vision, natural language processing and speech recognition. Beyond these traditional fields, deep learning has been expended to quantum chemistry, physics, neuroscience, and more recently to combinatorial optimization (CO). Well-known CO problems are Travelling Salesman Problem, assignment problems, routing, planning, Bayesian search, and scheduling. CO is basically used every day in finance and revenue management, transportation, manufacturing, supply chain, public policy, hardware design, computing and information technology. The workshop will bring together experts in mathematics (optimization, graph theory, sparsity, combinatorics, statistics), CO (assignment problems, routing, planning, Bayesian search, scheduling), machine learning (deep learning, supervised, self-supervised and reinforcement learning) and specific applicative domains (e.g. finance, transportation, hardware design, computing and information technology) to establish the current state of these emerging techniques and discuss the next directions. Besides, such generalization of deep learning techniques to CO problems will also push forward the mathematical analysis of the properties of these learning systems like generalization and transfer, stochastic optimization and dynamic predictivity that make the success of these techniques.

Geometry and Combinatorics from Root Systems
22 Mar 2021 - 26 Mar 2021 • Providence, RI, United States
Organizer:
ICERM
Abstract:
The purpose of the workshop is to bring together a diverse group of researchers working on combinatorial and geometric aspects related to spaces with symmetries. The workshop will cover problems arising from various flavors of Schubert Calculus and enumerative geometry on flag manifolds, and problems from geometric representation theory and combinatorial Hodge theory. The topics covered include the study of Littlewood-Richardson coefficients, quantum cohomology and quantum K theory of flag manifolds, Maulik-Okounkov stable envelopes and characteristic classes, conformal blocks, and combinatorics related to moduli spaces, Macdonald theory, and quiver polynomials, Soergel bimodules, Hodge theory of matroids. These are trends in a rapidly developing area, and our aim is to facilitate interactions among researchers who work on different problems but employ similar techniques, at the intersection of algebraic geometry, combinatorics, and representation theory.

AIM Workshop: Analytic combinatorics in several variables
17 May 2021 - 21 May 2021 • San Jose, United States
Organizer:
American Institute of Mathematics, San Jose
Abstract:
This workshop, sponsored by AIM and the NSF, will be devoted to bringing researchers with expertise in asymptotic integrals, computer algebra and topology of complex varieties into contact with those working on analytic combinatorics in several variables (ACSV), in order to make progress on the technical infrastructure of ACSV results.
