Fourth-order elliptic equations, often characterised by the inclusion of the biharmonic operator (Δ²), play a pivotal role in the mathematical modelling of complex physical systems. They arise in ...
A simple invariant characterization of the scalar fourth-order ordinary differential equations which admit a variational multiplier is given. The necessary and sufficient conditions for the existence ...
