Mathematical Analysis of Recent Analytical Approximations to the Collapse of an Empty Spherical Bubble
(American Institute Of Physics, 2013-02)
We analyze the Rayleigh equation for the collapse of an empty bubble and provide an explanation for some recent analytical approximations to the model. We derive the form of the singularity at the second boundary point and ...

Approximate expression for the energy of a D-dimensional anharmonic oscillator
(Iop Publishing Ltd, 2003-02-14)
An approximate expression is constructed for the energy of an anharmonic potential with centrifugal barrier. In order to obtain such an analytical expression, the quasi-exact solvability is used and then a fitting of these ...

Approximate analytic expression for the eigenenergies of the anharmonic oscillator V(x)=Ax6+Bx2
(American Physical Soc, 1995-12-01)
An approximate analytic expression for the eigenenergies of the anharmonic oscillator V(x)=Ax6+Bx2 is introduced, starting from particular analytic solutions which are valid when certain relations between the parameters A ...

Approximate analytic expression for the Skyrmions crystal
(World Scientific, 2018-01)
We find approximate solutions for the two-dimensional nonlinear ∑-model with Dzyalioshinkii-Moriya term, representing magnetic Skyrmions. They are built in an analytic form, by pasting different approximate solutions found ...
