A logical expression that is written as a conjunction,

LaTeX: C_1 \wedge C_2 \wedge \ldots \wedge C_m,

where LaTeX: \wedge is the conjunction (logical and). Each LaTeX: C_i is called a clause and has the form

LaTeX: L_{i_1} \vee L_{i_2} \vee \ldots \vee L_{i_n},

where LaTeX: \vee is the disjunction (logical inclusive or) and each LaTeX: L_i is a literal -- a proposition or its negation.
