SUMMARY:Small representations of integers by integral quadratic form (Lenny Fukshansky\, CMC)
DESCRIPTION:Given an isotropic integral quadratic form which assumes a value t\, we investigate the distribution of integer points at which this value is assumed. Building on the previous work about the distribution of small-height zeros of quadratic forms\, we produce bounds on height of points outside of some algebraic sets in a quadratic space at which the form assumes the value t. Our bounds on height are explicit in terms of heights of the form\, the space\, the algebraic set and the value t. Joint work with W. K. Chan. \nThe Fall 2018 organizational meeting for the ANTC seminar will be held at noon in the same room\, preceding the talk.

SUMMARY:An Algebra of Arcs and Knots on a Surface (Helen Wong\, CMC)
DESCRIPTION:The end of the previous century saw radical changes to three-dimensional topology\, which arose from two completely different approaches. One breakthrough came from Bill Thurston’s introduction of hyperbolic geometry into the field. The second one came from the Vaughn Jones’s discovery of a new “quantum” invariant for knots that brought in insight and techniques from mathematical physics and non-commutative algebra. It is widely believed that the two approaches are related. \nIn this talk\, we will focus on a point of connection introduced over five years ago by J. Roger and T. Yang.  They defined an algebra of arcs and knots on a surface that is both  obviously related to the quantum invariants and motivated by hyperbolic geometry.  We will give a overview of what’s known about this algebra of arcs and knots on a surface.  Warning: there will be lots of pictures of arcs and knots on surfaces.

SUMMARY:Diffusion\, Social Networks\, and Logic (Pavel Naumov\, CMC)
DESCRIPTION:Once a new commercial product\, technology\, political opinion\, or social norm is adopted by a few people\, these few often put peer pressure on others to consider adopting it as well. Those who adopt next put even more pressure on the rest of the population. This cascading “epidemic” effect is often called diffusion in social networks. There are many natural questions that can be asked about diffusion. Which initial group of people should get “infected” by a new product to ensure its adoption by the largest possible group? Which group should be convinced that an idea is bad\, in order to avoid its wide spread? How does marketing affect the diffusion? In this talk I will introduce the most commonly used mathematical model of diffusion and talk about several of my papers on logical systems that capture properties of this model.

SUMMARY:Inversions for reduced words (Sami Assaf\, USC)
DESCRIPTION:The number of inversions of a permutation is an important statistic that arises in many contexts\, including as the minimum number of simple transpositions needed to express the permutation and\, equivalently\, as the rank function for weak Bruhat order on the symmetric group. In this talk\, I’ll describe an analogous statistic on the reduced expressions for a given permutation that turns the Coxeter graph into a ranked poset with unique maximal element. This statistic simplifies greatly when shifting our paradigm from reduced expressions to balanced tableaux\, and I’ll use this simplification to give an elementary proof computing the diameter of the Coxeter graph for the long permutation. \nThis talk is elementary and assumes no background other than passing familiarity with the symmetric group.

SUMMARY:Quandle coloring quivers (Sam Nelson\, CMC)
DESCRIPTION:Given a finite quandle $X$\, a set $S \subset \mathrm{Hom}(X\,X)$ of quandle endomoprhisms\, and an oriented knot or link $L$\, we construct a quiver-valued invariant of oriented knots and links. This quiver categorifies the quandle counting invariant in the most literal sense and can be used to define many enhancements of the counting invariant. This is joint work with Harvey Mudd College student Karina Cho.

SUMMARY:Snow Business: Scientific Computing in the Movies and Beyond (Joseph Teran\, UCLA)
DESCRIPTION:New applications of scientific computing for solid and fluid mechanics problems include simulation of virtual materials in movie visual effects and virtual surgery. Both disciplines demand physically realistic dynamics for materials like water\, smoke\, fire\, and soft tissues. New algorithms are required for each area. Teran will speak about the simulation techniques required in these fields and will share some recent results including: simulated surgical repair of biomechanical soft tissues; extreme deformation of elastic objects with contact; high resolution incompressible flow; and clothing and hair dynamics. He will also discuss a new algorithm used for simulating the dynamics of snow in Disney’s animated feature film\, “Frozen.”

SUMMARY:Reaction-Diffusion Equations under Perturbations of the Domain (Professor Jose Arrieta\, Universidad Complutense de Madrid\, Spain)
DESCRIPTION:We analyze the behavior of the asymptotic dynamics of dissipative reaction-diffusion equations with Neumann boundary conditions when the domain where the equation is posed undergoes certain perturbation. We will focus on the behavior of the stationary solutions\, their local unstable manifolds and the attractors. \nWe will consider “regular” perturbations of the domain\, that is\, perturbations for which the spectra of the Laplace operator behaves continuously. In this case\, it turns out that if all the equilibria of the unperturbed system are nondegenerate (hyperbolic)\, then both the equilibria and their local unstable manifolds behave continuously under the perturbation. Exploiting the gradient properties of the flow we will show that the “attractors” also behave continuously. \nWe may also consider some “non-regular” perturbations of the domain. In this situation\, the problem needs to be studied and the technique adapted for each particular case. An interesting example of non regular perturbations is the “dumbbell domain” which consists in two domains joined by a very thin channel which degenerates to a line segment. We will describe the results obtained for this perturbation.
