mu (μ)(mu)

mu (μ) is a number which can be written as 0/0, 0*∞, ∞-∞, 00, 1∞, ∞0, (-1)∞, 0i, etc. Conventional mathematics treats this quantity as "undefined". It may also be interpreted as an operator to undo wavefunction collapse and then re-collapse with arbitrary choice, allowing one to jump to alternate logical branches.
