In mathematics, the **structure space** of a commutative Banach algebra is an analog of the spectrum of a C*-algebra. It consists of all multiplicative linear functionals on the algebra. The Gelfand representation of the Banach algebra is a map taking the Banach algebra elements to continuous functions on the structure space.

### Famous quotes containing the words space and/or structure:

“The limitless future of childhood shrinks to realistic proportions, to one of limited chances and goals; but, by the same token, the mastery of time and *space* and the conquest of helplessness afford a hitherto unknown promise of self- realization. This is the human condition of adolescence.”

—Peter Blos (20th century)

“Slumism is the pent-up anger of people living on the outside of affluence. Slumism is decay of *structure* and deterioration of the human spirit. Slumism is a virus which spreads through the body politic. As other “isms,” it breeds disorder and demagoguery and hate.”

—Hubert H. Humphrey (1911–1978)
