RT8.3. Finite Groups: Projection to Irreducibles

Representation Theory: Having classified irreducibles in terms of characters, we adapt the methods of the finite abelian case to define projection operators onto irreducible types. Techniques include convolution and weighted averages of representations. At the end, we state and prove the Plancherel Formula (Parseval's Identity using irreducibles). Course materials, including problem sets with solutions, are available at http://mathdoctorbob.org/UR-RepTheory.html
