Division subspaces and integrable kernels
In this note we prove that the reproducing kernel of a Hilbert space
satisfying the division property has integrable form, is locally of trace
class, and the Hilbert space itself is a Hilbert space of holomorphic
functions.Comment: 11 page
Convergence of resonances on thin branched quantum wave guides
We prove an abstract criterion stating resolvent convergence in the case of
operators acting in different Hilbert spaces. This result is then applied to
the case of Laplacians on a family X_\eps of branched quantum waveguides.
Combining it with an exterior complex scaling we show, in particular, that the
resonances on X_\eps approximate those of the Laplacian with ``free''
boundary conditions on , the skeleton graph of X_\eps.Comment: 48 pages, 1 figur
Learning Bayesian Networks with the bnlearn R Package
bnlearn is an R package which includes several algorithms for learning the
structure of Bayesian networks with either discrete or continuous variables.
Both constraint-based and score-based algorithms are implemented, and can use
the functionality provided by the snow package to improve their performance via
parallel computing. Several network scores and conditional independence
algorithms are available for both the learning algorithms and independent use.
Advanced plotting options are provided by the Rgraphviz package.Comment: 22 pages, 4 picture
