Blow-up exponents and a semilinear elliptic equation for the fractional Laplacian on hyperbolic spaces

Tommaso Bruno, Effie Papageorgiou

Let $H^{n}$ be the $n$ -dimensional real hyperbolic space, $Δ$ its nonnegative Laplace--Beltrami operator whose bottom of the spectrum we denote by $λ_{0}$ , and $σ \in (0, 1)$ .…

Surjectivity of convolution operators on harmonic $N A$ groups

Effie Papageorgiou

Let $μ$ be a radial compactly supported distribution on a harmonic $N A$ group. We prove that the right convolution operator $c_{μ} : f \mapsto f * μ$ maps the space of smooth $\mathfrak…
