Elasticity Problem for a Layer with a Cylindrical Cavity Under Periodic Loading

Journal of Mechanical Engineering
In aerospace and mechanical engineering, elements that are loaded by periodic loads (periodic function) are used. In problems for a layer with cylindrical inhomogeneities, it is difficult to take such loads into account.

The Lamé family of connections on the projective line

, 2008
International audienceThis paper deals with rank two connections on the projective line having four simple poles with prescribed local exponents 1/4 and -1/4. This Lamé family of connections has been extensively studied in the literature.

On Darboux's Approach to R-Separability of Variables

Symmetry, Integrability and Geometry: Methods and Applications, 2011
We discuss the problem of R-separability (separability of variables with a factor R) in the stationary Schrödinger equation on n-dimensional Riemann space.

Spatially localized trains of soliton in attractive Bose-Einstein condensates with periodic potential

Partial Differential Equations in Applied Mathematics
We investigate the spatial profiles of periodic localized modes in attractive Bose-Einstein condensates, by solving the mean-field Gross-Pitaevskii equation in the presence of elliptic-type periodic potential.

Application of the Method of Summation Identities in Solving a Boundary-Value Problem for the Lame Equations [PDF]

Учёные записки Казанского университета: Серия Физико-математические науки, 2016
A boundary-value problem on an interval for a one-dimensional system of the Lame equations corresponding to a physical problem of propagation of an elastic wave through the gradient layer is considered. In this case, the coefficients of the equations are

Semi-smooth Newton methods for optimal control of the dynamical Lamé system with control constraints.

, 2013
International audienceOptimal control problems governed by the dynamical Lamé system with additional constraints on the controls are analyzed. Different types of control action are considered: distributed, Neumann boundary and Dirichlet boundary control.
