    • Abstract
      Nucleotide rearrangements occur at both evolutionary and developmental levels, and are often studied through model organisms such as ciliate species Oxytricha and Stylonychia. These processes can be modeled by 4-regular rigid vertex graphs, called assembly graphs. They are closely related to double occurrence words, chord diagrams, and circle graphs. Edges of these graphs represent double-stranded DNA molecules, while vertices correspond to DNA recombination sites. We present graph invariants of these assembly graphs and investigate genome-wide the range of scrambled gene architectures that describe the precursor-product relationships. We find that there are two general patterns, reoccurring genome wide, that describe over 90% of the Oxytricha’s scrambled genes. We further investigate the patterns of interleaving genes and find that there are specific star-like graph structures that describe most complex interleaving patterns.

    • Abstract
      We study the problem of a trader who wants to maximize the expected reward from liquidating a given stock position. We model the stock price dynamics as a geometric pure jump process with local characteristics driven by an unobservable finite-state Markov chain and the liquidation rate. This refl ects uncertainty about the state of the market and feedback effects from trading. We use stochastic fi ltering to reduce the optimization
      problem under partial information to an equivalent one under complete information. This leads to a control problem for piecewise deterministic Markov processes (in short PDMP).
      We apply control theory for PDMPs to our problem. In particular, we derive the optimality equation for the value function and characterize the value function as unique viscosity solution of the associated dynamic programming equation. Finally we provide adetailed analysis on some specific examples.

      This is a joint work with Zehra Eksi, Rüdiger Frey and Michaela Szölgyenyi.

    • Abstract
      Hybrid High-Order (HHO) methods are a class of new generation numerical schemes for PDEs with several advantageous features, including: (i) support of general polytopal meshes in arbitrary space dimension, (ii) arbitrary approximation order; (iii) compliance with the physics, including robustness with respect to the variations of physical coefficients and reproduction of key continuous properties at the discrete level; (iv) reduced computational cost thanks to hybridization, static condensation, and compact stencil.
      In this presentation we address some recent developments concerning the application of HHO methods to nonlinear problems

      Viene mostrato come alcuni risultati di approssimazione tramite operatori di tipo campionamento svolgono un ruolo importante nell’ambito della ricostruzione di segnali/immagini e vengono discusse alcune loro applicazioni ad immagini CT per la diagnosi di patologie vascolari dell’aorta addominale.

    • A bernstein-type result for the minimal surface equation

    • Mercoledì 25 gennaio 2017 alle ore 17:15 precise, Aula seminari 6° piano
    • Abstract
      We prove the following Bernstein-type theorem: if $u$ is a solution to the minimal surface equation over $R^N$, such that $N-1$ partial derivatives are bounded on one side (not necessarily the same), then $u$ is an affine function. Besides its novelty, our theorem also provides a new, simple and self-contained proof of celebrated results of J. Moser and of E. Bombieri e E. Giusti.
