Global self-similar solutions for Hardy-Hénon equations with linear and quasilinear diffusion

Razvan Gabriel Iagar, Ariel Sánchez, Erik Sarrion-Pedralva

Global self-similar solutions to the parabolic Hardy-Hénon equation $u_{t} = Δ u^{m} + ∣ x ∣^{σ} u^{p}, (x, t) \in R^{N} \times (0, \infty),$ are classified in the range of exponents $m…

First Dirichlet eigenvalue and exit time moment spectra comparisons

Vicente Palmer, Erik Sarrion-Pedralva

We prove explicit upper and lower bounds for the Poisson hierarchy, the averaged $L^{1}$ -moment spectra $\{\dfrac{\mathcal{A}_k\left(B_R^M\right)}{\text{vol}\left(S_R^M\right)}\}_{k=…

First Eigenvalue of the Laplacian of a Geodesic Ball and Area-Based Symmetrization of its Metric Tensor

Vicent Gimeno, Erik Sarrion-Pedralva

Given a Riemmanian manifold, we provide a new method to compute a sharp upper bound for the first eigenvalue of the Laplacian for the Dirichlet problem on a geodesic ball of radius…
