I am reasonably sure he means the affine plane over a field.

comment Proving $\mathscr L(C_G(H)) \subseteq \mathfrak c_{\mathfrak g}(\mathfrak h) = \{ \mathrm x \in \mathfrak g \mid [\mathrm x, \mathfrak h] = 0\}$
I gave this answer recently, it seems like the same question.

comment Placing n points in a MxM square grid
Are you required to do this "on-line", as in the paper? Be aware that this means the following: Your algorithm does not know how many points have to be placed before it runs! This makes the whole thing much more difficult than in the case where the algorithm knows how many points have to be placed from the beginning.

answered For an element $x$ in an algebraic group $G$, why do we have $\mathscr{L}(C_G(x))\subset\mathfrak{c}_{\mathfrak{g}}(x)$?

As a second comment, do you have some references for this branching rule? That'd be really great. Thanks so much already, though!

comment Orthogonal invariants of an irredubile GL-representation
The partition corresponding to the invariants should be $(0)$, not $(1)$ - that'd mean that it's the case if $\lambda$ has only even summands, right?
