In mathematics and mathematical logic, Boolean algebra is a branch of algebra.It differs from elementary algebra in two ways. First, the values of the variables are the truth values true and false, usually denoted 1 and 0, whereas in elementary algebra the values of the variables are numbers.
For a complete boolean algebra infinite de-Morgan's laws hold. A Boolean algebra is complete if and only if its Stone space of prime ideals is extremally disconnected. Sikorski's extension theorem states that if A is a subalgebra of a Boolean algebra B, then any homomorphism from A to a complete Boolean algebra C can be extended to a morphism ...

propositional logic, Boolean algebra, Heyting algebra: is false when A is true and B is false but true otherwise. may mean the same as (the symbol may also indicate the domain and codomain of a function; see table of mathematical symbols).
Boolean function with two different minimal forms. The Blake canonical form is the sum of the two. In Boolean logic , a formula for a Boolean function f is in Blake canonical form ( BCF ), [ 1 ] also called the complete sum of prime implicants , [ 2 ] the complete sum , [ 3 ] or the disjunctive prime form , [ 4 ] when it is a disjunction of all ...
The term "Boolean algebra" honors George Boole (1815–1864), a self-educated English mathematician. He introduced the algebraic system initially in a small pamphlet, The Mathematical Analysis of Logic, published in 1847 in response to an ongoing public controversy between Augustus De Morgan and William Hamilton, and later as a more substantial book, The Laws of Thought, published in 1854.
In mathematics, a Boolean function is a function whose arguments and result assume values from a two-element set (usually {true, false}, {0,1} or {-1,1}). [1] [2] Alternative names are switching function, used especially in older computer science literature, [3] [4] and truth function (or logical function), used in logic.
The Staff Selection Commission is expected to release the SSC CGL result 2024 soon on its official website - ssc.gov.in. The Commission released the SSC CGL answer key on October 3, 2024. The last date to send objections was October 8, 2024. The Commission will consider the objections and analyze the representation received from the candidates.
