Unitary monodromy of Lamé differential operators
, 2007 The classical second order Lamé equation contains a so-called accessory parameter B. In this paper we study for which values of B the Lamé equation has a monodromy group which is conjugate to a subgroup of SL(2, R) (unitary monodromy with indefinite ...

Integrability of Hamiltonian systems and the Lamé equation
, 2005 We study the integrability of Hamiltonian systems with two degrees of freedom. We investigate the normal variational equations and obtain a necessary condition for integrability of these systems.

Vertex green's functions of a quarter-plane: Links between the functional equation, additive crossing and Lamé functions [PDF]
, 2021 In our previous work (Assier & Shanin, QJMAM, 2019), we gave a new spectral formulation in two complex variables associated with the problem of plane-wave diffraction by a quarter-plane.

Solving the Problem of Elasticity for a Layer with N Cylindrical Embedded Supports
Computation, 2023 The main goal of deformable solid mechanics is to determine the stress–strain state of parts, structural elements, and their connections. The most accurate results of calculations of this state allow us to optimize design objects. However, not all models

New Journal of Physics, 2023 A possible use of matter-wave dark-soliton crystal produced by a Bose–Einstein condensate (BEC) with ring geometry, to store soliton states in the quantum memory of a free boson gas, is explored.

An Analysis of the Stress–Strain State of a Layer on Two Cylindrical Bearings
ComputationA spatial problem of elasticity theory is solved for a layer located on two bearings embedded in it. The bearings are represented as thick-walled pipes embedded in the layer parallel to its boundaries.

Existence and Orbital Stability of Cnoidal Waves for a 1D Boussinesq Equation
International Journal of Mathematics and Mathematical Sciences, 2007 We will study the existence and stability of periodic travelling-wave solutions of the nonlinear one-dimensional Boussinesq-type equation Φtt−Φxx+aΦxxxx−bΦxxtt+ΦtΦxx+2ΦxΦxt=0.

Lamé equations with algebraic solutions
, 2004 In this paper we study Lamé equations Ln,By=0 in so-called algebraic form, having only algebraic functions as solution. In particular we provide a complete list of all finite groups that occur as the monodromy groups, together with a list of examples of ...
