Proofs by example
</div><div>Speaker: Benjamin Matschke (Boston University)</div><div><br></div><div>Abstract: We study the proof method ``proof by example" in which a general statement can be proved by verifying it for a single example. This strategy can indeed work if the statement in question is an algebraic identity and the example is ``generic". This talk addresses the problem of constructing a practical example, which is sufficiently generic, for which the statement can be verified efficiently, and which allows for a numerical margin of error.<br> Our method is based on diophantine geometry, in particular an arithmetic Bezout theorem, an arithmetic Nullstellensatz, and a new effective Liouville-Lojasiewicz type inequality for algebraic varieties. As an application we discuss theorems from plane geometry and how to prove them by example.</div><div><br></div><div><br></div><div><br></div><div>
