Winter 2007 QG Seminar Errata

John Baez

Here's a list of errors we've found in the Winter 2007 Quantum Gravity Seminar notes. If you discover any more errors, please let me know, and we'll eventually try to correct them, or at least add them to this list.

Quantization and Cohomology

• Week 10 - On page 1, Schrödinger's equation should be

  i h d/dt ψ_t = H ψ_t

  with a slash through the h and a hat on the H.

Classical versus Quantum Computation

• Week 14 - In the λ-theory for commutative rings we really need to include negation (or subtraction) as an operation, since the typed λ-calculus is not expressive enough to say there exists an additive inverse for each element.
