That is how far I've got by now. --Lambiam 08:45, 20 May 2023 (UTC) Note that for n=-1 the value _is_ a square, so the real problem is to prove there aren't any additional squares. Proving something occurs exactly once might be more difficult than proving something can't happen at all. --RDBury 16:30, 20 May 2023 (UTC)
The Picard group of the spectrum of a Dedekind domain is its ideal class group.; The invertible sheaves on projective space P n (k) for k a field, are the twisting sheaves (), so the Picard group of P n (k) is isomorphic to Z.
That is, the physical universe is not merely described by mathematics, but is mathematics — specifically, a mathematical structure. Mathematical existence equals physical existence, and all structures that exist mathematically exist physically as well. Observers, including humans, are "self-aware substructures (SASs)".
Richard Phillips Feynman (/ ˈ f aɪ n m ə n /; May 11, 1918 – February 15, 1988) was an American theoretical physicist.He is best known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, and in particle physics, for which he proposed the parton model.
