and relations. Additional features of the Second Edition include: An intense focus on the formal settings of proofs and their techniques, such as constructive proofs, proof by contradiction, and combinatorial proofs New sections on applications of elementary number theory, multidimensional induction, coun...
The techniques in the textbook call for a sequence of conditional derivations and I would guess some universal instantiation or generalizations. What am I missing to connect these 2 proofs? What is the link between a predicate logic proof and a math proof written in English? I see that there ...

In this article, we present computerized proof techniques of Gosper, WilfZeilberger and Zeilberger that can be used for enhancing the teaching and learning of topics in discrete mathematics. We demonstrate by examples how one can use these computerized proof techniques to raise students'' interests...

For some time it was thought that certain theorems, like the prime number theorem, could only be proved using "higher" mathematics. However, over time, many of these results have been reproved using only elementary techniques.Two-column proof A two-column proof published in 1913...
I’m teaching Discrete Mathematics this semester. It is our “intro to proofs” class. One of the proof techniques the students learn is proof by induction. I told the class that usually the base case for induction proofs are easy and that most of the work occurs in the inductive step. ...
"To address this situation and establish certainty, Hales turned to computers, using techniques of formal verification. He and a team of collaborators wrote out the entire proof in extraordinary detail using strict formal logic, which a computer program then checked with perfect rigor. This paper ...
Additionally, we use similar proof techniques to improve upon the bounds on the online ordered size Ramsey number of a path given by Pérez-Giménez, Pralat, and West.doi:10.48550/arXiv.2006.03703József Balogh... J Balogh,FC Clemen,E Heath,... 被引量: 0发表: 2020年 Ramsey-remainder for...
Since we use only no wastage as a efficiency desideratum, which is much weaker than Pareto-efficiency, we need to develop our own proof techniques to establish our results. We start off by showing an elementary lemma which shows that at every preference profile, if a mechanism gives every ...
