We are – almost all of us – deeply attracted to the idea of being normal. But what if our idea of ‘normal’ isn’t normal? A plea for a broader definition of an important term. If you like our films, take a look at our shop (we ship worldwide): https://goo.gl/ojRR53 Join our mailing list: h

Every vector is a linear combination of the same n simple vectors!
Learning Objectives: 1) Identify the so called "standard basis" vectors 2) Geometrically express a vector as linear combination of the standard basis vectors 3) Algebraically express a vector as a linear combination of the standard basis vectors 4) Express a vector as a matrix-vector produ

Linear Algebra for Computer Scientists. 10. The Standard Basis
This computer science video is one of a series on linear algebra for computer scientists. In this video you will learn about the standard basis, otherwise known as the natural basis. The standard basis is an orthonormal set of vectors which can be used in linear combination to easily cre

Coordinate Systems From Non-Standard Bases | Definitions + Visualization
We've all used the standard coordinate system where (x,y) means x to the right and y up. However, for any subspace and a basis of that subspace, we can define a coordinate system. The same vector can thus be written in multiple coordinate systems. We describe what exactly we mean by this,

Purity for the Brauer group of singular schemes - Česnavičius - Workshop 2 - CEB T2 2019
Kęstutis Česnavičius (Université Paris-Sud) / 27.06.2019 Purity for the Brauer group of singular schemes For regular Noetherian schemes, the cohomological Brauer group is insensitive to removing a closed subscheme of codimension ≥ 2. I will discuss the corresponding statement for scheme

Kęstutis Česnavičius - Grothendieck–Serre in the quasi-split unramified case
Correction: The affiliation of Lei Fu is Tsinghua University. The Grothendieck–Serre conjecture predicts that every generically trivial torsor under a reductive group scheme G over a regular local ring R is trivial. We settle it in the case when G is quasi-split and R is unramified. To ov

The goal of these lectures is to sketch a general framework to study orbital integrals over equal characteristic local fields by means of moduli spaces of Hitchin type following the main lines of the proof of the fundamental lemma for Lie algebras. After recalling basic elements of the pro

Jarosław Buczyński (6/29/17) Bedlewo: Constructions of k-regular maps using finite local schemes
A continuous map R^m → R^N or C^m → C^N is called k-regular if the images of any k distinct points are linearly independent. Given integers m and k a problem going back to Chebyshev and Borsuk is to determine the minimal value of N for which such maps exist. The methods of algebraic topolo

Bhatt-Morrow-Scholze have defined integral refinements $Z_p(i)$ of the syntomic cohomology of Fontaine-Messing and Kato. These objects arise as filtered Frobenius eigenspaces of absolute prismatic cohomology and should yield a theory of "p-adic étale motivic cohomology" -- for example, the

La conjecture de conservativité affirme qu'un morphisme entre motifs constructibles est un isomorphisme s'il en est ainsi de l'une des ses réalisations classiques (de Rham, ℓ-adique, etc.). Il s'agit d'une conjecture centrale dans la théorie des motifs ayant des conséquences concrètes sur

Writing Vectors in Different Coordinate Systems
Description: Coordinate systems as we have conventionally thought of them are based on the standard basis vectors. But if we have some other basis, we can define a sensible notion of a coordinate system as well. Learning Objectives: 1) Write a vector in a specified basis into the standar
