Anti-symmetry of the second eigenfunction of the fractional Laplace operator in a 3-D ball
Rui A. C. Ferreira
In this work we extend a recent result by Dyda et. al. [B. Dyda, A. Kuznetsov, M. Kwasnicki, Eigenvalues of the fractional Laplace equation in the unit ball, J. Lond. Math. Soc. (2…
Toeplitz minors and specializations of skew Schur polynomials
David García-García, Miguel Tierz
We express minors of Toeplitz matrices of finite and large dimension in terms of symmetric functions. Comparing the resulting expressions with the inverses of some Toeplitz matrice…
An entropic interpolation problem for incompressible viscid fluids
Marc Arnaudon, Ana Bela Cruzeiro, Christian Léonard +1
In view of studying incompressible inviscid fluids, Brenier introduced in the late 80's a relaxation of a geodesic problem addressed by Arnold in 1966. Instead of inviscid fluids,…
On the second Dirichlet eigenvalue of some nonlinear anisotropic elliptic operators
Francesco Della Pietra, Nunzia Gavitone, Gianpaolo Piscitelli
Let be a bounded open set of , . In this paper we mainly study some properties of the second Dirichlet eigenvalue of the anisotropic -Lap…
Edge connectivity and the spectral gap of combinatorial and quantum graphs
Gregory Berkolaiko, James B. Kennedy, Pavel Kurasov +1
We derive a number of upper and lower bounds for the first nontrivial eigenvalue of a finite quantum graph in terms of the edge connectivity of the graph, i.e., the minimal number…
A new look at Bernoulli's inequality
Rui A. C. Ferreira
In this work, a generalization of the well known Bernoulli inequality is obtained by using the theory of discrete fractional calculus. As far as we know our approach is novel.
