Abstract:
We study the nonexistence of nontrivial solutions for the nonlinear
elliptic system
where
,
,
,
, and
is the fractional operator
of mixed orders
, defined by
Here,
,
,
is the fractional Laplacian
operator of order
with respect to the variable
,
and
,
,
is the fractional Laplacian
perator of order
with respect to the variable
.
Via a weak formulation approach, sufficient conditions are provided in terms
of space dimension and system parameters.
