- TL;DR Summary
- The state is supposed to describe everything about a particle, but are vectors always sufficient to do this?

Elementary question: Is there ever a case where the solutions for a wave equation turn out not to be a vector (in Hilbert space of infinite complex-valued dimensions, or a restriction to a subspace thereof) , but something else -- say, (higher-order) tensors or bivectors, or some such?

My apologies that the question lacks a specific example; if I had one, I would be answering my own question.

I suspect the answer is "no", but I would like to make sure. Thanks.
