In this paper, using an orthogonal matrix in space $$R^{n}$$ , the notion of a nonlocal biharmonic operator is introduced. For the corresponding nonlocal biharmonic equation, solvability of boundary value problems with fractional conformable derivatives is studied. For the considered problems, theorems on the existence and uniqueness of solutions are proved. Necessary and sufficient conditions for solvability of the studied problems are obtained and integral representations of solutions are presented.
