Singular perturbation by bending for an adhesive obstacle problem [PDF]
, 2015 A free boundary problem arising from materials science is studied in the one-dimensional case. The problem studied here is an obstacle problem for the non-convex energy consisting of a bending energy, tension and an adhesion energy. If the bending energy,

The effect of arbitrarily small rigidity on the free oscillations of the Earth
Annals of Geophysics, 1997 The system of propagator equations for an elastic solid becomes singular as the shear modulus becomes vanishingly small. In computational applications there is severe loss of precision as the limit of zero shear modulus is approached.

Absolutely stable difference scheme for a general class of singular perturbation problems
Advances in Difference Equations, 2020 This paper presents an absolutely stable noniterative difference scheme for solving a general class of singular perturbation problems having left, right, internal, or twin boundary layers. The original two-point second-order singular perturbation problem

Dynamic model reduction: An overview of available techniques with application to power systems [PDF]
Serbian Journal of Electrical Engineering, 2012 This paper summarises the model reduction techniques used for the reduction of large-scale linear and nonlinear dynamic models, described by the differential and algebraic equations that are commonly used in control theory. The groups of methods

Beyond Adiabatic Elimination: Effective Hamiltonians and Singular Perturbation [PDF]
, 2015 Adiabatic elimination is a standard tool in quantum optics, that produces an effective Hamiltonian for a relevant subspace of states, incorporating effects of its coupling to states with much higher unperturbed energy.

Variational problems with singular perturbation [PDF]
, 2005 In this paper, we construct the local minimum of a certain variational problem which we take in the form $\mathrm{inf}\int_\Omega\left\{\frac{\epsilon}{2}kg^2|\nabla w|^2+\frac{1}{4\epsilon}f^2g^4(1-w^2)^2\right\}\,\mathrm{d}x$, where $\epsilon$ is a ...

Smooth approximation of singular perturbations [PDF]
Journal of Mathematical Analysis and Applications, 2003 One of the main advantages gained by the modern use of point interactions in mathematical physics is the exact solvability of the Schrödinger equation and, simultaneously, the possibility of understanding the underlying formulae simply in the language of the essentially self-adjoint extensions.
