How does one compute induced representations for modular representations?
I'm not sure what you mean... I am given all the character tables. Here's what I mean: $Ind^G_H(\rho)=\sum a_i\chi_i$. $(Ind^G_H(\rho),\chi_i)=a_i$, and so if we can compute all the $(Ind^G_H(\rho),\chi_i)'s$ then we're done. Frobenius reciprocity does indeed allow to compute those. I know what all the $\chi_i$'s are because I'm given the character tables of $G$ and $H$. Am I missing something? |

The etale fundamental group of a field
If you don't read French, the beginning of Milne's "Lectures on Etale Cohomology" gives a concise framework, relating algebraic stuff with topological stuff. The relevant material is just a couple of pages. |
