tHANK YOU GUYS, SOMEONE KNOW: 2 - Describe the free object over a given set X on the constant Pos (of partially ordened sets and isotone maps)
Hey guys, i need a HUGE favor, i need the resolution for this 5 questions, its a question of end this year my degree or stay one year just with a subject. Please I am begging, who knows the resolution please say me something.
Part 1: Mathematical Logic
2- Convert the formula into the prenex form: (square root of)x p(x,g) -> ( inverted E )y (square root of) z q (x,y)
3- Consider the language L with the symbol of equality and one array predicate symbol. Write the formula in this language which express there exist exactly one x such that p(x) holds
4- Verify, which any of the formulas ¬ A v B and A or B substituted for x makes the formula ( A -> x ) -> ( x -> B ) a tautology.
Part 2: Mathematical Structures
1 - find the subgroup of the group (Z, +, 0) generated by the set {20,25} .
2 - Describe the free object over a given set X on the constant Pos (of partially ordened sets and isotone maps)
