Understanding the problem

Read the background

For every positive order delta, the three-dimensional Bochner–Riesz multiplier is bounded on L3(R³). Interpolation and duality yield the conjectured strict Lp boundedness range for all 1 <= p <= infinity.

Why it matters

If correct, establishes the remaining central exponent and hence the full strict-order Bochner–Riesz multiplier range in three dimensions.

What counts as progress

Are the three-dimensional Bochner–Riesz multipliers bounded throughout the conjectured strict-order range?
