The Jacobian meets Robespierre

Doodle for Mathober Day 23: Jacobian. Which, of course, made me think of Jacobins...

Talk about your sketchy puns.

Test functions and [tempered] distributions require the notion of topological vector space … distributions can be traced back to Green's functions in the 1830’s to solve ordinary differential equations … the 1936 work of Sergei Sobolev on hyperbolic PDE’s.

Laurent Schwartz introduced the term "distribution" by analogy with a distribution of electrical charge, possibly including not only point charges but also dipoles and so on.

tempered distribution

topological vector space

(^ if there is a dipole, there must be a notion of subtraction, hence the need for a vector, and to speak of this very conceptually, use a TVS)

A blog about mathematics.

Updated Multi-Variable Calculus! I finished the brief review of single-variable calculus! Although the notes for multi-variable calculus will not really have much to do with this review, it is important to know basic differentiation, integration, and parametrization!

**I also added some notes from Linear Algebra since vectors and properties of vectors will be used a lot in multi-variable calculus!

studying over break!

(sidenote: how come these pics only look clear when you click on them and zoom in? can someone help :/)
