  • Cowen, Carl C.; Gallardo-Gutiérrez, Eva A. (American Mathematical Society, 2017)
    A striking result by Nordgren, Rosenthal and Wintrobe states that the Invariant Subspace Problem is equivalent to the fact that any minimal invariant subspace for a composition operator Cφ induced by a hyperbolic automorphism ...
  • Lu, Kang (National Academy of Science of Ukraine, 2018)
    The self-dual spaces of polynomials are related to Bethe vectors in the Gaudin model associated to the Lie algebras of types B and C. In this paper, we give lower bounds for the numbers of real self-dual spaces in intersections ...
  • Aptekarev, Alexander I.; Bogolubsky, Alexey I.; Yattselev, Maxim I. (arXiv, 2016)
    Let $\widehat\sigma$ be a Cauchy transform of a possibly complex-valued Borel measure $\sigma$ and $\{p_n\}$ be a system of orthonormal polynomials with respect to a measure $\mu$, $\mathrm{supp}(\mu)\cap\mathrm{supp}(\s ...
  • Geller, William; Misiurewicz, Michał (World Scientific, 2018-02)
    Lorenz-like maps arise in models of neuron activity, among other places. Motivated by questions about the pattern of neuron firing in such a model, we study periodic orbits and their itineraries for Lorenz-like maps with ...
  • Cosper, David; Misiurewicz, Michał (2018)
    We prove that in certain one-parameter families of piecewise continuous piecewise linear interval maps with two laps, topological entropy stays constant as the parameter varies. The proof is simple and applies to a large ...
  • Graff, Grzegorz; Misiurewicz, Michał; Nowak-Przygodzki, Piotr (Taylor & Francis, 2018)
    Let f be a smooth map of the m-dimensional sphere Sm to itself, preserving the longitudinal foliation. We estimate from below the number of fixed points of the iterates of f, reduce Shub’s conjecture for longitudinal maps ...
  • Shen, Zhou; Levine, Michael; Shang, Zuofeng (IMS, 2018)
    We consider a semiparametric mixture of two univariate density functions where one of them is known while the weight and the other function are unknown. We do not assume any additional structure on the unknown density ...
  • Ramras, Daniel A. (Springer, 2018-03)
    We give a new description of Rosenthal’s generalized homotopy fixed point spaces as homotopy limits over the orbit category. This is achieved using a simple categorical model for classifying spaces with respect to families ...
  • Bleher, Pavel; Elwood, Brad; Petrović, Dražen (Springer, 2018)
    We prove the Pfaffian Sign Theorem for the dimer model on a triangular lattice embedded in the torus. More specifically, we prove that the Pfaffian of the Kasteleyn periodic-periodic matrix is negative, while the Pfaffians ...
  • Sarkar, Jyotirmoy (Springer, 2018)
    In the celebrated “Secretary Problem,” involving n candidates who have applied for a single vacant secretarial position, the employer interviews them one by one in random order and learns their relative ranks. As soon as ...
  • Wang, Honglang; Zhong, Ping-Shou; Cui, Yuehua; Li, Yehua (Wiley, 2018-03)
    We consider the problem of testing functional constraints in a class of functional concurrent linear models where both the predictors and the response are functional data measured at discrete time points. We propose test ...
  • Lu, Kang; Mukhin, Evgeny (World Scientific, 2018)
    We derive a number of results related to the Gaudin model associated to the simple Lie algebra of type G2. We compute explicit formulas for solutions of the Bethe ansatz equations associated to the tensor product of an ...
  • Fry, Brendan C.; Coburn, Ehren Brant; Whiteman, Spencer; Harris, Alon; Siesky, Brent; Arciero, Julia (Elsevier, 2018-11)
    Impaired oxygen delivery and tissue perfusion have been identified as significant factors that contribute to the loss of retinal ganglion cells in glaucoma patients. This study predicts retinal blood and tissue oxygenation ...
  • Müller, Ursula U.; Peng, Hanxiang; Schick, Anton (Springer, 2017)
    We present a new, efficient maximum empirical likelihood estimator for the slope in linear regression with independent errors and covariates. The estimator does not require estimation of the influence function, in contrast ...
  • DiVolo, Matteo; Morozova, Ekaterina; Lapish, Christopher; Kuznetsov, Alexey; Gutkin, Boris (2017-06-30)
    Alcoholism is the third leading cause of preventable mortality in the world. In the last decades a large body of experimental data has paved the way to a clearer knowledge of the specific molecular targets through which ...
  • Han, Fang; Ji, Hongkai; Ji, Zhicheng; Wang, Honglang (Institute of Mathematical Statistics, 2017)
    In many applications, linear models fit the data poorly. This article studies an appealing alternative, the generalized regression model. This model only assumes that there exists an unknown monotonically increasing link ...
  • Bleher, Pavel; Liechty, Karl (Springer, 2018-02)
    We obtain asymptotic formulas for the partition function of the six-vertex model with domain wall boundary conditions and half-turn symmetry in each of the phase regions. The proof is based on the Izergin–Korepin–Kuperberg ...
  • Barnett, William H.; Abdala, Ana P.; Paton, Julian F. R.; Rybak, Ilya A.; Zoccal, Daniel B.; Molkov, Yaroslav I. (Elsevier, 2017-01)
    The respiratory central pattern generator must respond to chemosensory cues to maintain oxygen (O2) and carbon dioxide (CO2) homeostasis in the blood and tissues. To do this, sensorial cells located in the periphery and ...
  • Feigin, B.; Jimbo, M.; Mukhin, Eugene (IOP, 2017)
    We identify the Taylor coefficients of the transfer matrices corresponding to quantum toroidal algebras with the elliptic local and non-local integrals of motion introduced by Kojima, Shiraishi, Watanabe, and one of the ...
  • Shang, Zuofeng; Cheng, Guang (2017)
    In this paper, we explore statistical versus computational trade-off to address a basic question in the application of a distributed algorithm: what is the minimal computational cost in obtaining statistical optimality? ...
