    • Well-balanced discontinuous Galerkin method for shallow water equations with constant subtraction techniques on unstructured meshes 

      Du, Huijing; Liu, Yingjie; Liu, Yuan; Xu, Zhiliang (Springer US, 2019-10)
      The classical Saint–Venant shallow water equations on complex geometries have wide applications in many areas including coastal engineering and atmospheric modeling. The main numerical challenge in simulating Saint–Venant ...
    • Why is isotropy so prevalent in spatial statistics? 

      Ma, Chunsheng (American Mathematical Society, 2007-03)
      There are many reasons for the popular use of the isotropic or geometrically anisotropic covariance function and variogram in spatial statistics. A less known reason demonstrated in this paper is that an isotropic or ...
    • Zeta function of self-adjoint operators on surfaces of revolution 

      Lu, Tianshi; Jeffres, Thalia D.; Kirsten, Klaus (IOP Publishing, 2015-04-10)
      In this article we analyze the zeta function for the Laplace operator on a surface of revolution. A variety of boundary conditions, separated and unseparated, are considered. Formulas for several residues and values of the ...
    • Zeta function on surfaces of revolution 

      Jeffres, Thalia D.; Kirsten, Klaus; Lu, Tianshi (IOP Publishing, 2012-08-31)
      In this paper we applied the contour integral method for the zeta function associated with a differential operator to the Laplacian on a surface of revolution. Using the WKB expansion, we calculated the residues and values ...
