Minor: Added choice of convention in GRE

v0.1.3

Add Weinberg convention example

Typeset update

Updated the way to generate aliases (use such as Esc - (type)tu - Esc). The new way should work for both v13 and pervious versions of Mathematica, whereas the old way broke in v13.

The release to match 1306.1295v2

v0.1

fix `Dispatch` change of behavior in Mathematica 10

v0.1-beta.5

Major changes:

• Simp can now go into common functions like Exp, Sin, Cos, Power.
• Added TSeries which expand tensor series safely.
• Added a lot of examples.

v0.1-beta.4

Dump incremental changes and fixes.

v0.1-beta.3

Fixed a regression of tensor simplification, when there are terms on exponential (or maybe other non-polynomial functions).

Other small tweaks.

Minor fixes

This is a minor release with the following fixes:

• Added DeleteSym
• Added check against nested indices.
• Fixed a bug where Dta raise / lower indices.
• Decomposition now by default use {U1, D1} and {U2, D2}.
• Renamed Asym to AntiSym
• Combine SimpF, SimpH, SimpM into Simp.

preparing for the initial github release

We are preparing for the initial github release.

Compared to the earliest announced version on arXiv, there are quite a few enhancements. Including

• Decomposition of indices now works more consistently.
• The tensor display mechanism is updated. Now the displayed tensors can be edited.
• Added documentation in nb file. Easier to run than retyping the LaTeX documentation.
• Performance and modularity improvements for Ibp[].
• More unit test cases added.
• Now the code is hosted at GitHub.
