The less significant role of large-scale environment than optical AGN in nearby, isolated elliptical galaxies
(2018)
Context. The formation and evolution of elliptical galaxies in low-density environments are less understood than classical elliptical galaxies in high-density environments. Isolated galaxies are defined as galaxies without ...
Applications of the Lie symmetries to complete solution of a bead on a rotating wire hoop
(2018-02-01)
The existence of Lie symmetries in differential equations can generate transformations in the dependent and independent variables and obtain new equations that may be easier to integrate. In particular, in some situations, ...
Integrability and Dynamics of Quadratic Three-Dimensional Differential Systems Having an Invariant Paraboloid
(2016-07-01)
Invariant algebraic surfaces are commonly observed in differential systems arising in mathematical modeling of natural phenomena. In this paper, we study the integrability and dynamics of quadratic polynomial differential ...
Modular Hypergeometric Residue Sums of Elliptic Selberg Integrals

Comments on "Free vibration of super elliptical plates with constant and variable thickness by Ritz method"
(Academic Press Ltd - Elsevier Science Ltd, 2010-10)
Free vibration of super elliptical plates with constant and variable thickness by Ritz method has been reported. the shape of the plate in the x y plane can be defined by the super elliptical function. Calculating the area ...

Using weak forms to derive asymptotic expansions of elliptic equations with high-contrast cofficients
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Matemáticas, 2014-07-01)
In this work we review some recent results on approximation of solutions of elliptic problems with high-contrast coefficients. In particular, we detail the derivation of asymptotic expansions for the solution in terms of ...
