چکیده
Let X and Y be two closed connected Riemannian manifolds of the same dimension and φ : S∗X 7→ S∗Y a contact diffeomorphism. We show that the index of an elliptic Fourier operator Φ associated with φ is given by ∫ B(X) e 0Â(T ∗X) −

متن کاملOn the numerical solution of integral equations of the fourth kind with higher index: differentiability and tractability index-3
In this paper, we consider a particular class of integral equations of the fourth kind and show that tractability and differentiability index of the given system are 3. Tractability and dierentiability index are introduced based on the-smoothing property of a Volterra integral operator and index reduction procedure, respectively. Using the notion of index, we give sucient conditions for the exi...
متن کاملA finite difference method for the smooth solution of linear Volterra integral equations
The present paper proposes a fast numerical method for the linear Volterra integral equations withregular and weakly singular kernels having smooth solutions. This method is based on the approx-imation of the kernel, to simplify the integral operator and then discretization of the simpliedoperator using a forward dierence formula. To analyze and verify the accuracy of the method, weexamine samp...
متن کاملContact Degree and the Index of Fourier Integral Operators
An elliptic Fourier integral operator of order 0, associated to a homogeneous canonical diffeomorphism, on a compact manifold is Fredholm on L2. The index may be expressed as the sum of a term, which we call the contact degree, associated to the canonical diffeomorphism and a term, computable by the Atiyah-Singer theorem, associated to the symbol. The contact degree is shown to be defined for a...
