Representation of bilinear forms in non-Archimedean Hilbert space by linear operators. (English) Zbl 1150.47408
Summary: The paper considers representing symmetric, non-degenerate, bilinear forms on some non-Archimedean Hilbert spaces by linear operators. Namely, upon making some assumptions it will be shown that if $$\phi$$ is a symmetric, non-degenerate bilinear form on a non-Archimedean Hilbert space, then $$\phi$$ is representable by a unique self-adjoint (possibly unbounded) operator $$A$$.
