Hi I recently learned about
http://www.mathjax.org/ which is a great library to render Latex snippets inside HTML. See for example the abstract contained by http://projecteuclid.org/euclid.aos/1388545673 I would like to do the "same" thing with PDF, which means I have an XML containing Latex snippets, e.g. <p> We study sparse principal components analysis in high dimensions, where $p$ (the number of variables) can be much larger than $n$ (the number of observations), and analyze the problem of estimating the subspace spanned by the principal eigenvectors of the population covariance matrix. We introduce two complementary notions of $\ell_{q}$ subspace sparsity: row sparsity and column sparsity. We prove nonasymptotic lower and upper bounds on the minimax subspace estimation error for $0\leq q\leq1$. The bounds are optimal for row sparse subspaces and nearly optimal for column sparse subspaces, they apply to general classes of covariance matrices, and they show that $\ell_{q}$ constrained estimates can achieve optimal minimax rates without restrictive spiked covariance conditions. Interestingly, the form of the rates matches known results for sparse regression when the effective noise variance is defined appropriately. Our proof employs a novel variational $\sin\Theta$ theorem that may be useful in other regularized spectral estimation problems. </p> and then I would like to use XSL-FO and FOP to generate PDF. Is that possible somehow? Or any other ideas how I could generate such a PDF?
