Simplifying a rational expression with rational exponents

👉 Learn how to divide with rational powers. To divide with numbers/expressions with rational exponents, we apply the basic rules of exponents. If the two numbers/expressions are the same, we simply take one of the number and raise it to the power of the difference between the exponents of

Set Theory (Part 13): Constructing the Rational Numbers

Please feel free to leave comments/questions on the video and practice problems below! In this video, we will use the integers to construct the rational numbers as a quotient set, just as we constructed the integers. We will also introduce arithmetic on the rational numbers and show that

Choice Functions and Length: Why you can't measure everything you choose

I haven't talked about the axiom of choice in a while, and the relationship between choice functions and length (or size) and why you can't measure everything you choose seemed like a good way to do so. The interplay between choice functions and how one can construct sets for which measure

Nick Addington - Rational points and derived equivalence - WAGON

For smooth projective varieties over Q, is the existence of a rational point preserved under derived equivalence? First I'll discuss why this question is interesting, and what is known. Then I'll show that the answer is no, giving two counterexamples: an abelian variety and a torsor over i

Marcello Bernardara: Semiorthogonal decompositions and birational geometry of geometrically rational

Abstract:This is a joint work in progress with A. Auel. Let S be a geometrically rational del Pezzo surface over a field k. In this talk, I will show how the k-rationality of S is equivalent to the existence of some semiorthogonal decompositions of its derived category. In particular, the

Higher Algebra 11: p-adic completion (corrected)

In this video we introduce the notion of p-adic completion and p-adic equivalence of spectra. We characterize those notions in concrete terms and give examples. Finally we cover the Hasse-square, which can be used to recover X from it completions and its rationalisation. All the material i

How to use the LCD to help us solve a rational equation

👉 Learn how to solve proportions. Two ratios are said to be proportional when the two ratios are equal. Thus, proportion problems are problems involving the equality of two ratios. When given a proportion problem with an unknown, we usually cross-multiply the two ratios and then solve for
