Zhegalkin algebra
In mathematics, Zhegalkin algebra is a set of Boolean functions defined by the nullary operation taking the value 1 {\displaystyle 1} , use of the binary operation of conjunction ∧ {\displaystyle \land } , and use of the binary sum operation for modulo 2 ⊕ {\displaystyle \oplus } . The constant 0 {\displaystyle 0} is introduced as 1 ⊕ 1 = 0 {\displaystyle 1\oplus 1=0} .
