Thus the concepts of Boolean

**algebra**and Boolean ring with unit are equivalent .If B and C are Boolean algebras and h : B + C , then h is said to be a

homomorphism , or a Boolean

**algebra**homomorphism , if h ( x ^ y ) = h ( x ) ^ h (y ) , h ...

Let S be a compact Hausdorff space and C ( S ) be the

continuous functions on S . Let A be a closed subalgebra of C ( S ) which

contains the unit e and contains , with f , its complex conjugate f defined by f ( s )

= f ( s ) .
