Given $sin(0,1)$, we consider the problem of minimizing the fractional
Gagliardo
seminorm in $H^s$ with prescribed condition outside the ball
and under the further constraint of attaining zero value in a given set $K$.
We investigate how the energy changes in dependence of such set.
In particular, under mild regularity conditions, we show
that adding a set $A$ to $K$ increases the energy of at most the measure of $A$
(this may be seen as a perturbation result for small sets $A$).
Also, we point out a monotonicity feature of the energy with respect
to the prescribed sets and the boundary conditions.
