Tensors in general relativity | Riemannian geometry | Lorentzian manifolds
In the theory of Lorentzian manifolds, particularly in the context of applications to general relativity, the Kretschmann scalar is a quadratic scalar invariant. It was introduced by Erich Kretschmann. (Wikipedia).

Dyson-Schwinger equations provide one of the most powerful non-perturbative approaches to quantum field theories. The quartic analogue of the Kontsevich model is a toy model for QFT in which the tower of Dyson-Schwinger equations splits into one non-linear equation for the planar two-point

Scalars, Vectors, and Vector Operations
What are all these funny little arrows? They're vectors! And we will use them to represent every single force we discuss in physics, so we need to know how to draw them, add them, subtract them, split them up into X and Y components, the whole nine yards. We also need to know the differenc

Geometric Algebra, First Course, Episode 06: Scalar Product and the Metric.
The scalar product has many applications in elementary Physics. We extend our Multivector to have the standard scalar product, allowing us to compute magnitudes and angles between vectors. In doing so, we choose our basis vectors to be orthogonal. We recognize that we live in Euclidean Sp

P. Burkhardt-Pointwise lower scalar curvature bounds for C0 metrics via regularizing Ricci flow (vt)
We propose a class of local definitions of weak lower scalar curvature bounds that is well defined for C0 metrics. We show the following: that our definitions are stable under greater-than-second-order perturbation of the metric, that there exists a reasonable notion of a Ricci flow starti
