Cohomologies of real Lie algebras

With this form you can request a selection of computations that are needed for a determination of real Lie algebra cohomologies. To specify the type of the computation to be done, you must fill out the form below; most computations require some additional parameters, and you will ask to fill out other forms to specify these.
What do you wish to be shown or computed ?

Here you can select the complexification of the requested real Lie algebra. If you want to use the real simple part with non-simple complectification, (i.e. the underlying real Lie algebra), input only one simple part and use the box on the right hand side. (A selection of a large algebra has as the consequence a long computation. It can be aborted by the server.)
