Feb 16, 2016 at 2:03 comment added Qfwfq Ok, I see! BTW, I just opened a related question :)
Feb 16, 2016 at 1:58 comment added Hamed @Qfwfq Of course, you're right. For the purpose of this question translation invariance is redundant, and I should've excluded it. I included it honestly as a force of habit. The reason we keep saying translation invariant in our work is, another avenue of the study is finding a basis for for these polynomials, in other words: what subset of Jack polynomials is the basis of this space (in this part of the work keeping the exact form of the polynomials is important so we do not do this coordinate change).
Feb 16, 2016 at 0:40 comment added Qfwfq @Hamed: alright but, up to a linear change of variables, you have a polynomial $f(z_1,\cdots, z_n)$ which is periodic of period $1$ in the variable $z_n$, hence constant in $z_n$, so essentially a polynomial in $n-1$ variables...
Feb 14, 2016 at 21:29 comment added Hamed @JasonStarr I actually tried that book, it is a little bit above my pay-grade. Another way I could've asked this question is: A step-by-step program to get ready to understand that book.
Feb 14, 2016 at 21:26 comment added Hamed @Qfwfq Oh, a polynomial $f(z_1, \cdots, z_n)$ is translation invariant if for any constant $c\in \mathbb{C}$, you have $f(z_1+c, \cdots, z_n+c)=f(z_1, \cdots, z_n)$. Another way to define it is through the operator $D=\sum \partial_i$, then $f$ is translation invariant if $Df=0$. Edit: We are interested in multi-variable polynomials (these $z_i$ are in physics the coordinates of a particle).
Feb 14, 2016 at 19:24 comment added Qfwfq Probably I'm misunderstanding your terminology, but how can a (non constant) polynomial $P(x)$ be translation invariant?
Feb 14, 2016 at 14:56 comment added Jason Starr Nakajima has a textbook about Hilbert schemes: "Lectures on Hilbert Schemes of Points on Surfaces". Here is a link to the webpage for the book: bookstore.ams.org/ulect-18
Feb 14, 2016 at 7:04 comment added roy smith read mumford's lectures on curves on an algebraic surface.
