Sussex PDEs 16/09/14 – Frederic Helein

The blackboard is spacetime…

It’s like if N was transparent.

Names in technical terminology

Cauchy data

…use D’Harrivel’s notation…

Feynman’s rule

Spatial aspect

Size of the Cauchy data

space of solutions to the linear problem Lv=0

How to write down the dynamics…

When a key observation was made, in which an important link or connection was made, its “Advantages” were written down as

1) Gives directly a generating series (Spoken: “I say directly, but you have some work to do”)

2) More regularity (Spoken: “This process gives you more regularity, but you stay in the same space”)

3) Generalises to space-time
