Spectral and stochastic properties of the $f$-Laplacian, solutions of PDE's at infinity, and geometric applications
Weighted Laplacians Feller property stochastic completeness essential spectrum gradient Ricci solitons
2011/8/26
Abstract: The aim of this paper is to suggest a new viewpoint to study qualitative properties of solutions of semilinear elliptic PDE's defined outside a compact set. The relevant tools come from spec...
Equivariant inverse spectral theory and toric orbifolds
Laplacian symplectic orbifold toric moment polytope equivariant spectrum constant scalar curvature
2011/8/25
Abstract: Let O be a symplectic toric 2n-dimensional orbifold with a fixed T^n-action and with a toric Kahler metric g. We previously explored whether, when O is a manifold, the equivariant spectrum o...
Restriction and spectral multiplier theorems on asymptotically conic manifolds
Restriction spectral multiplier theorems asymptotically conic manifolds
2011/2/22
The classical Stein-Tomas restriction theorem is equivalent to the statement that the spectral measure dE() of the square root of the Laplacian on Rn is bounded from Lp(Rn) to Lp′
(Rn) for 1 p 2...
We construct a spectral sequence converging to symplectic homology of a Lefschetz fibration whose E1 page is related to Floer homology of the monodromy symplectomorphism and its iterates. We use this ...
On the spectral geometry of a Riemannian Legendre foliation

2010/12/8
We obtain geometric characterizations of isospectral minimal Riemannian Legendre foliations on compact Sasakian manifolds of constant '-sectional curvature.
Approximate variances for tapered spectral estimates
Asymptotic variance data taper (smoothed) periodogram
2010/12/15
We propose an approximation of the asymptotic variance that removes a certain discontinuity in the formula for the raw and the smoothed periodogram in case a data taper is used. It is based on an appr...
Spectral Analysis of Virus Spreading in Random Geometric Networks
Spectral Analysis Random Geometric Networks Virus Spreading
2010/4/2
In this paper, we study the dynamics of a viral spreading process in random geometric graphs (RGG). The spreading of the viral process we consider in this paper is closely related with the eigenvalues...
