What is the fundamental mathematical requirement cited as the underlying cause of wave-particle duality?

Answer

The non-commutativity of operators representing observables like position and momentum.

The underlying cause is the mathematical structure where observables like position ($\hat{x}$) and momentum ($\hat{p}$) do not commute, forcing a duality required by quantum mechanics.
