5 Tautologies classical propositional calculus "Interesting articles for students
An important role is played in the correct inference schemes such complex sentences that each sentence falling under such a scheme is always a true compound sentence. Schemes such we call tautologies of classical propositional calculus, or simply statements (laws) of classical propositional calculus.
Example sentences podpadającego the above diagram:
called sceper the law of double negation. Mentioned that tautologies (logical expression always true, at any valuation propositional variables) play a special role in the plants, so the question is, how to check the authenticity of any logical expressions.
There is an effective method (algorithm), which allows to check in a finite number of steps, if any schema and built with connectives and propositional variables (letters), and parentheses is the law (tautology) plants, or it is not.
This method is commonly called method of verifying the zero - jedynkowego. The method of application is very simple. Each variable in any schema and represents a sentence true or false: variable, so in the scheme and replace once the symbol 0, and the second time a symbol of the first proceeding sceper in this way, with each variable, we obtain sceper the diagram a certain number of specific substitutions. The number of these substitutions is finite.
