It is natural to expect Q{#}::IndexInherit; B_{m n}::Symmetric; A_{m n}::AntiSymmetric; ex:= Q( B_{m n} ) A_{m n}; canonicalise(_); to produce zero, but that does not work yet because `Q` does...
The Cadabra Jupyter kernel can be run on Windows using WSL, and then accessed using the Jupyter notebook interface, but it is easier to use VS Code's Jupyter notebook support....
(Anti)symmetrising a set of objects modulo subgroup symmetries is a general operation which should be handled in a more central place.
I am building a Jupyter kernel for the Cadabra computer algebra system (https://cadabra.science), using the Xeus library to do the communication. Most works well, but if I make even the...
I am seeing weird behaviour with `setScissor` when turning on dynamic resolution (on Android). It looks like the left/bottom positions are interpreted according to the full resolution. So as the...
Should either make the checks solid so that joins never work with mixed indices, or make it always do the same thing consistently. ``` {a,b}::Indices(flat, position=fixed). {\mu, \nu}::Indices(curved, position=fixed). \gamma{#}::GammaMatrix(metric=\eta);...
I am seeing a crash on any attempt to render something on an iPad Air 2, with stack trace ``` Crashed: FEngine::loop 0 libsystem_kernel.dylib 0x6bbc __pthread_kill + 8 1 libsystem_pthread.dylib...
