We initiate a systematic study of natural differential operators in Riemannian geometry whose leading symbols are not of Laplace type. In particular, we define a discrete leading symbol for such operators which may be computed pointwise, or from spectral asymptotics. We indicate how this can be appl
## Abstract The present paper is devoted to the asymptotic and spectral analysis of an aircraft wing model in a subsonic air flow. The model is governed by a system of two coupled integroโdifferential equations and a two parameter family of boundary conditions modelling the action of the selfโstrai
In this second paper of a four-part series, we construct the characteristic determinant of a two-point differential operator \(L\) in \(L^{2}[0,1]\), where \(L\) is determined by \(\ell=-D^{2}+q\) and by independent boundary values \(B_{1}, B_{2}\). For the solutions \(u(\cdot ; \rho)\) and \(v(\cdo
## Abstract We consider a class of nonโselfadjoint operators generated by the equation and the boundary conditions, which govern small vibrations of an ideal filament with nonโconservative boundary conditions at one end and a heavy load at the other end. The filament has a nonโconstant density and
