I do not know if this is the proper rubric to ask this question, but I picked the one that seemed the most relevant.(adsbygoogle = window.adsbygoogle || []).push({});

I have noticed some superficial resemblance between the tensor product and the ultraproduct definitions. Does this resemblance go any further?

While I am on the subject of tensor products: when there is a physical interaction, is there necessarily entanglement involved, even for a short time?
