e/Semihilbert space

Information
has gloss	eng: In mathematics, a semi-Hilbert space is a generalization of a Hilbert space in functional analysis, in which, roughly speaking, the inner product is required only to be positive semi-definite rather than positive definite, so that it gives rise to a seminorm rather than a vector space norm.

has gloss	epo: En matematiko, duon-hilberta spaco estas ĝeneraligo de hilberta spaco en funkcionala analitiko. En duon-hilberta spaco la ena produto estas postulita nur al esti pozitive duon-difinita sed ne pozitive difinita, tiel ke ĝi donas la duonnormon sed ne normon.
