Depth formula conjecture for squarefree powers of wheel edge ideals
Let be the wheel graph on vertices, let be its edge ideal in , and let denote its matching number. For integers and , consider the -th squarefree power . Depth conjecture for wheel squarefree powers. For all such and ,
equivalently,
The conjecture is suggested by the complete computations reported for wheels with in the relevant low-power cases, together with the top-power cases for . It would give a uniform depth and projective-dimension formula throughout the full range of squarefree powers, beyond the computational evidence currently recorded.
