• Computation of plane potential flow around multi-element airfoils using the Schottky-Klein prime function 

  DeLillo, Thomas K.; Green, Christopher C. (Elsevier, 2023-08-01)

  Potential flow is computed around multi-element airfoils in two dimensions using numerical conformal mapping combined with the calculus of the Schottky-Klein prime function. The corners at the trailing edges of the airfoils ...

• Ramond-Ramond fields and twisted differential K-theory 

  Grady, Daniel; Sati, Hisham (International Press of Boston, Inc., 2023-03-30)

  We provide a systematic approach to describing the Ramond-Ramond (RR) fields as elements in twisted differential K-theory. This builds on a series of constructions by the authors on geometric and computational aspects of ...

• Multivariate exponential power Lévy processes and random fields 

  Ma, Chunsheng (Elsevier Ltd, 2023-06-01)

  Two multivariate exponential power Lévy processes are introduced in this paper via compound Poisson representations, which are so termed because their characteristic exponents are the linear combination of certain positive ...

• Kähler manifolds and the curvature operator of the second kind 

  Li, Xiaolong (Springer Link, 2023-03-22)

  This article aims to investigate the curvature operator of the second kind on Kähler manifolds. The first result states that an m-dimensional Kähler manifold with $$\frac{3}{2}(m^2-1)$$-nonnegative (respectively, ...

• Manifolds with nonnegative curvature operator of the second kind 

  Li, Xiaolong (World Scientific Publishing Co., 2023-01-13)

  We investigate the curvature operator of the second kind on Riemannian manifolds and prove several classification results. The first one asserts that a closed Riemannian manifold with three-positive curvature operator of ...

• Modeling the spread of the Coronavirus 

  Jaeger, Adam (Wichita State University, 2020-05-03)

• Computing the logarithmic capacity of compact sets having (infinitely) many components with the charge simulation method 

  Liesen, Jörg; Nasser, Mohamed M. S.; Sète, Olivier (Springer Link, 2023-02-28)

  We apply the charge simulation method (CSM) in order to compute the logarithmic capacity of compact sets consisting of (infinitely) many “small” components. This application allows to use just a single charge point for ...

• Concept for a space-based near-solar neutrino detector 

  Solomey, Nickolas; Folkerts, Jonathan; Meyer, Holger; Gimar, Caleb; Novak, Jarred; Doty, Brian; English, Trent; Buchele, Lynn; Nelsen, Austin; McTaggart, Robert; Christl, Mark J. (Elsevier B.V., 2023-04-01)

  The concept of putting a neutrino detector in close orbit of the Sun has been unexplored until very recently. The primary scientific return is to vastly enhance our understanding of the solar interior, which is a major ...

• Eigenvalue estimates on Quaternion-Kähler manifolds 

  Li, Xiaolong; Wang, Kui (Springer, 2023-01-09)

  We prove lower bound estimates for the first nonzero eigenvalue of the Laplacian on a compact quaternion-Kähler manifold. For the closed or Neumann case, the lower bounds depend on dimension, diameter, and lower bound of ...
