  • Complexity in biomedicine
    Caterina La Porta, Università degli Studi di Milano
    giovedì 18 luglio 2019 alle ore 10:00, Dipartimento di Matematica - 7° piano, Politecnico di Milano
    ABSTRACT
    In this talk, I will discuss our recent advances in understanding phenotypic plasticity of cancer cells using a combination of experiments, analysis of big data and computational models of complex regulatory networks. Next, I will discuss our results on protein aggregation in neurodegenerative pathologies, such as Alzheimer's and Huntington's disease.

    In particular, I will report on the importance of protein clearance from the endoplasmic reticulum to drive protein aggregation and on our recent results on huntingtin heterogenous aggregation in which mutated forms of the protein are able to form oligomers with non-mutated forms.

  • The LLV decomposition for hyper-Kaehler cohomology
    Radu Laza, Stony Brook
    venerdì 12 luglio 2019 alle ore 14:30, Sala di Rappresentanza, Via C. Saldini 50
    ABSTRACT
    Looijenga—Lunts and Verbitsky (LLV) have shown that the cohomology of
    a compact hyper-Kaehler manifold admits the action of a big Lie
    algebra g, generalizing the usual sl(2) Hard Lefschetz action. We
    compute the LLV decomposition of the cohomology for the known classes
    of hyper-Kaehler manifolds (i.e. K3^n, Kim_n, OG6, and OG10). As an
    application, we easily recover the Hodge numbers of the exceptional
    example OG10. In a different direction, we establish the so-called
    Nagai’s conjecture (on the nilpotency index for higher degree
    monodromy operators) for the known cases. More interestingly, based
    on the known examples, we conjecture a new restriction on the
    cohomology of compact hyper-Kaehler manifolds, which in particular
    implies the vanishing of the odd cohomology as soon as the second
    Betti number is large enough relative to the dimension.
    This is joint work with M. Green, Y. Kim, and C. Robles.
  • Preconditioning of multiphysics problems with applications to the biomechanics of the brain
    Kent - Andre Mardal, University of Oslo and Simula Research Laboratory
    giovedì 11 luglio 2019 alle ore 14:00, Aula consiglio VII piano, Edificio 14, Dipartimento di Matematica POLITECNICO DI MILANO
    ABSTRACT
    In this talk we will discuss preconditioning algorithms for monolithic schemes of coupled problems involving the coupling of porous and viscous flow as well as fluid-structure interaction and dimension reduction problems.
    We explore how fractional Laplacian solvers may be utilized to obtain parameter robust schemes. The schemes are discussed in the context of biomechanical modelling of the waste clearance processes in the brain that is believed to fail in various forms of dementia such as Alzheimer's and Parkinson's diseases.

  • Implementing zonal harmonics with the Fueter principle
    Amedeo Altavilla, Università Politecnica delle Marche
    lunedì 8 luglio 2019 alle ore 14:00, Aula Seminari del 3 piano, Edificio La Nave, Via Ponzio 32-34
    ABSTRACT
    The Fueter theorem is a well studied result in hypercomplex analysis which gives a procedure to construct hyperholomorphic functions (in some sense), starting from complex holomorphic ones.
    In this talk I will show how to adapt such result in order to obtain formulas to represent real zonal harmonics in every dimension.
  • Shift invariant subspaces of the quaternionic space of slice $L^2$ functions
    Alessandro Monguzzi, Università degli Studi di Milano Bicocca
    lunedì 8 luglio 2019 alle ore 15:00, Aula Seminari del 3 piano, Edificio La Nave, Via Ponzio 32-34
    ABSTRACT
    I will give a characterization of the closed shift invariant subspaces of the quaternionic space of slice $L^2$ functions. As a consequence, the inner-outer factorization theorem for the quaternionic Hardy space $H^2$ on the unit ball is obtained. Therefore, I will present some properties of inner and outer functions in the quaternionic setting, providing in particular sufficient conditions as well as necessary ones for functions to be inner or outer.

    This talk is based on joint works with Giulia Sarfatti and Daniel Seco.
  • A scalable computational framework for large-scale simulation of fluid-driven fracture propagation
    Bianca Giovanardi, MIT, Cambridge, MA, USA
    venerdì 5 luglio 2019 alle ore 14:00, aula Saleri VI piano
    ABSTRACT
    Fluid-driven crack propagation concerns several areas of engineering, including structural, geotechnical, and petroleum engineering. The development of simulation tools for pressurized cracks propagating in realistic scenarios needs to tackle the complexity arising from the non-linear hydro-mechanical coupling of the fluid and the cracked solid in a suitable framework for large-scale applications.
    In this talk, I will introduce the governing equations of hydraulic fracture and discuss well-known propagation regimes where the prob- lem can be treated analytically. I will then present a computational ap- proach to model the hydro-mechanical coupling of the fracturing solid and the fluid flow inside the propagating cracks. Benchmarks in 2D and 3D demonstrate the capability of the computational framework to successfully deal with a priori unknown and arbitrarily intricate crack paths, and with the need for large-scale simulations.
    Time permitting, I will describe other recent efforts in developing advanced computational algorithms for large-scale simulation of complex material response, including elastic instabilities and material failure.

  • A prescribed anisotropic mean curvature equation modeling the corneal shape: A paradigm of nonlinear analysis
    Colette De Coster, Univ. Valenciennes
    martedì 2 luglio 2019 alle ore 15:15, Aula seminari 3° piano
    ABSTRACT
    In this talk, we survey some recent results concerning the Dirichlet problem for the prescribed anisotropic mean curvature equation
    \begin{equation*}
    {\rm -div}\left({\nabla u}/{\sqrt{1 + |\nabla u|^2}}\right) = -au + {b}/{\sqrt{1 + |\nabla u|^2}},
    \end{equation*}
    in a bounded Lipschitz domain $\Omega \subset \mathbb{R}^n$, with $a,b>0$ parameters.
    This equation appears in the description of the geometry of the human cornea, as well as in the modeling theory of capillarity phenomena for compressible fluids.

    In this talk, we show how various techniques of nonlinear functional analysis can successfully be applied to derive a complete picture of the solvability patterns of the problem.
  • The mathematics of spreading droplets
    Lorenzo Giacomelli, Università La Sapienza, Roma
    lunedì 24 giugno 2019 alle ore 16:30 precise, Sala Consiglio, 7 piano, Edificio La Nave, Via Ponzio 31-33
    ABSTRACT
    Wetting phenomena at small scales are an area where chemistry,
    physics, mathematics, and engineering intersect. In recent years,
    driven also by molecular dynamics, new concepts have been introduced
    to describe the statics and dynamics of wetting, allowing new
    insights into the old problems of surface forces. Among these
    problems, two prominent ones are an appropriate mathematical modeling
    of the moving contact line where liquid, solid, and surrounding vapor
    meet, and how such models influence the macroscopic properties of the
    flow. After a general framing -- the classical setting of droplets'
    statics and dynamics, diffuse and sharp interface models, classical
    and new descriptions of the contact line -- I shall review the PDE
    theory for one of such models -- the so-called thin-film equation --, mainly focusing on the two aforementioned problems and on some of the most interesting current challenges.
