Construction de valeurs propres doubles du laplacien de Hodge-de Rham
Pierre Jammes
On any compact manifold of dimension greater than 3, we exhibit a metric whose first positive eigenvalue for the Laplacian acting on p-form is of multiplicity 2. As a corollary, we…
Effondrements et petites valeurs propres des formes différentielles
Pierre Jammes
Short survey about small eigenvalues of the Hodge Laplacian under bounded curvature collapsing.
Minoration conforme du spectre du laplacien de Hodge-de Rham
Pierre Jammes
Let be a n-dimensional compact manifold, with . For any conformal class C of riemannian metrics on M, we set $μ_k^c(M,C)=\inf_{g\in C}μ_{[\frac n2],k}(M,g)\Vol(M,g)^{…
Prescription du spectre du laplacien de Hodge-de Rham dans une classe conforme
Pierre Jammes
For any compact manifold of dimension n>=5, we prescribe the volume and any finite part of the spectrum of the Hodge Laplacian acting on diffential forms of degree 1<p<n-1 (exept f…
