In commutative algebra, the Rees algebra of an ideal in a ring is defined to be

This construction has special interest in algebraic geometry since the projective scheme defined by the Rees algebra of an ideal in a ring is the blowing-up of the spectrum of the ring along the subscheme defined by the ideal.[1]
