Let $\Omega \subset \mathbb {R}^N$
($N\geq 3$
) be a $C^2$
bounded domain and $\Sigma \subset \partial \Omega$
be a $C^2$
compact submanifold without boundary, of dimension $k$
, $0\leq k \leq N-1$
. We assume that $\Sigma = \{0\}$
if $k = 0$
and $\Sigma =\partial \Omega$
if $k=N-1$
. Let $d_{\Sigma }(x)=\mathrm {dist}\,(x,\Sigma )$
and $L_\mu = \Delta + \mu \,d_{\Sigma }^{-2}$
, where $\mu \in {\mathbb {R}}$
. We study boundary value problems ($P_\pm$
) $-{L_\mu} u \pm |u|^{p-1}u = 0$
in $\Omega$
and $\mathrm {tr}_{\mu,\Sigma}(u)=\nu$
on $\partial \Omega$
, where $p>1$
, $\nu$
is a given measure on $\partial \Omega$
and $\mathrm {tr}_{\mu,\Sigma}(u)$
denotes the boundary trace of $u$
associated to $L_\mu$
. Different critical exponents for the existence of a solution to ($P_\pm$
) appear according to concentration of $\nu$
. The solvability for problem ($P_+$
) was proved in [3, 29] in subcritical ranges for $p$
, namely for $p$
smaller than one of the critical exponents. In this paper, assuming the positivity of the first eigenvalue of $-L_\mu$
, we provide conditions on $\nu$
expressed in terms of capacities for the existence of a (unique) solution to ($P_+$
) in supercritical ranges for $p$
, i.e. for $p$
equal or bigger than one of the critical exponents. We also establish various equivalent criteria for the existence of a solution to ($P_-$
) under a smallness assumption on $\nu$
.
