This paper deals with the existence of entire nontrivial solutions for fractional (p, q) systems
with critical Hardy terms in R N. Existence of solutions for system (S) is derived via the …

In this paper we establish some variants of the celebrated concentration–compactness
principle of Lions–CC principle briefly–in the classical and fractional Folland–Stein spaces …

We obtain a critical imbedding and then, concentration-compactness principles for fractional
Sobolev spaces with variable exponents. As an application of these results, we obtain the …

We establish a Lions-type concentration-compactness principle and its variant at infinity for
Musielak-Orlicz-Sobolev spaces associated with a double phase operator with variable …

We complete the study started in the paper [P. Pucci, L. Temperini, On the concentration-
compactness principle for Folland-Stein spaces and for fractional horizontal Sobolev …

In this paper, we are interested in a class of critical nonlocal problems with variable
exponents of the form:{M (T p (⋅,⋅)(u))[(− Δ) p (x, y) su+| u| p~(x)− 2 u]= λ f (x, u)+| u| q (x)− 2 …

In this paper, we investigate the existence of nontrivial solutions to the following fractional p-
Laplacian system with homogeneous nonlinearities of critical Sobolev growth:{(-Δ p) s⁢ u …

In this paper we study the existence of nontrivial solutions to the well-known Brezis–
Nirenberg problem involving the fractional p-Laplace operator in unbounded cylinder type …

We study bounded solutions to the fractional equation (-Δ) su+ u-| u| q-2 u= 0 in R n for n≥ 2
and subcritical exponent q> 2. Applying the variational approach based on concentration …

In this paper, we investigate the subelliptic nonlocal Brezis-Nirenberg problem on stratified
Lie groups involving critical nonlinearities, namely,\begin {align*}(-\Delta_ {\mathbb {G}, p}) …
