What does simplicial and non simplicial mean in the context of quantum mechanics?
What do they mean outside quantum mechanics and what makes you think they mean anything within quantum mechanics ?What does simplicial and non simplicial mean in the context of quantum mechanics?
It came up in this thread. The question arose in post #68What do they mean outside quantum mechanics and what makes you think they mean anything within quantum mechanics ?
Thanks, but I am having some problems deciphering it. Is there a straightforward defininition?
Another word for simplicial is polytope - it's a shape with pointy points like a square or a triangle. In a classical probabilistic theory, every mixture is a unique mix of pure states. But this is not true for a mixed density matrix, which can be written in many ways as a mixture of pure density matrices.Thanks, but I am having some problems deciphering it.
