Invariant Theory

Invariant theory is a branch of abstract algebra dealing with actions of groups on algebraic varieties, such as vector spaces, from the point of view of their effect on functions. Classically, the theory dealt with the question of explicit description of polynomial functions that do not change, or are invariant, under the transformations from a given linear group.

i love the interjections this is like shonen

[@beardymonger]

Excellent lecture, which university and course is this?

[@GiovannaIwishyou]

It must be Max Planck institute?

[@isaacAdam]

What do I need as prerequisite to study this theory?

[@GiovannaIwishyou]

I'd say Abstract Algebra of course (group theory, some Galois theory and commutative algebra).
