We investigate the existence of non-trivial weak solutions for the following p(x)-Kirchhoff bi-nonlocal elliptic problem driven by both p(x)-Laplacian and p(x)-Biharmonic operators



{ M(σ)(Δp(x)2u-Δp(x)u)=λϑ(x)| u |q(x)-2u(∫Ωϑ(x)q(x)| u |q(x)dx)r in Ω,u∈W2,p(.)(Ω)∩W01,p(.)(Ω), 
\left\{ {\matrix{   {M\left( \sigma  \right)\left( {\Delta _{p\left( x \right)}^2u - {\Delta _{p\left( x \right)}}u} \right) = \lambda \vartheta \left( x \right){{\left| u \right|}^{q\left( x \right) - 2}}u{{\left( {\int_\Omega  {{{\vartheta \left( x \right)} \over {q\left( x \right)}}{{\left| u \right|}^{q\left( x \right)}}dx} } \right)}^r}\,{\rm{in}}\,\Omega ,} \hfill  \cr    {u \in {W^{2,p\left( . \right)}}\left( \Omega  \right) \cap W_0^{1,p\left( . \right)}\left( \Omega  \right),} \hfill  \cr  } } \right.


under some suitable conditions on the continuous functions p, q, the non-negative function ϑ and M(σ), where



σ:=∫Ω| Δu |p(x)p(x)+| ∇u |p(x)p(x)dx.
\sigma : = \int_\Omega  {{{{{\left| {\Delta u} \right|}^{p\left( x \right)}}} \over {p\left( x \right)}} + {{{{\left| {\nabla u} \right|}^{p\left( x \right)}}} \over {p\left( x \right)}}dx.}


Our main results is obtained by employing variational techniques and the well-known symmetric mountain pass lemma.
