Lifting property

Lecture 3D - Lifting with a Pulley

Here is what pulleys are good for. They can apply the tension force multiple times for a "mechanical advantage". In this problem we go through the tensions and weights, and think about the effect on motion.

The Difference Between Mass and Weight

There is a common perception that weight and mass are basically the same thing. This video aims to tease out the difference between mass and weight by asking people what makes a car difficult to push. The standard answer is that it is difficult to push because it's heavy. But heaviness is

Physical Science 3.3c - Hydraulic Lift

The means by which a hydraulic lift creates a large force is explained in light of Pascal's Law and the transmission of pressure through a fluid.

Gilles Pisier: The lifting property for C*-algebras

Gilles Pisier - Propriétés de relèvement pour les 𝐶^∗-algèbres : du local au global ?

The main problem we will consider is whether the local lifting property (LLP) of a $C^*$-algebra implies the (global) lifting property (LP). Kirchberg showed that this holds if the Connes embedding problem has a positive solution, but it might hold even if its solution is negative. We will

Stable Homotopy Seminar, 7: Constructing Model Categories

A stroll through the recognition theorem for cofibrantly generated model categories, using it to construct (1) the Quillen/Serre model structure on topological spaces and (2) the levelwise model structure on spectra. The latter captures the idea that spectra are sequences of spaces, but no
