A class of integral-difference operators in a plane: Spectral analysis and application to thin films relaxation in an attractive field
Yuri B. Melnikov · Journal of Mathematical Physics · 2017
We use a recently developed technique to study in detail a model of thin film relaxation processes in a field. We consider the spectral structure of the operators underlying the dynamics of such processes and provide spectral estimates. Specific attention is paid to centre-symmetric attractive fields, located in circular domains.
