On the topology of deformation spaces of Kleinian groups

open access: yes, 2000
Let M be a compact, hyperbolizable 3-manifold with nonempty incompressible boundary and fundamental group G, and let AH(G) denote the space of (conjugacy classes of) discrete faithful representations of G into PSL(2, C). The components of the interior MP(

Algebraic discrete causal models [PDF]

open access: yes, 2010
The main feature of the paper is to show that Algebraic Statistics is a natural framework to address issues of causality and to help discern a total cause.

Incremental refinement of relevance rankings: Balancing relevance depth and scope

open access: yesJournal of the Association for Information Science and Technology, Volume 77, Issue 10, Page 1247-1270, October 2026.
Abstract Delivering both relevant and topically diverse results is a key challenge in information retrieval (IR). This study introduces a hybrid method that incrementally refines rankings by combining probabilistic topic modeling (latent dirichlet allocation [LDA]) with citation‐based pennant retrieval grounded in Relevance Theory (RT), optimizing for ...

Algebraic causality : Bayes nets and beyond [PDF]

open access: yes, 2007
The relationship between algebraic geometry and the inferential framework of the Bayesian Networks with hidden variables has now been fruitfully explored and exploited by a number of authors.

Lorentzian bordisms in algebraic quantum field theory [PDF]

open access: yes
It is shown that every algebraic quantum field theory has an underlying functorial field theory which is defined on a suitable globally hyperbolic Lorentzian bordism pseudo-category.

Analysis of Eigenvalue Clustering Leads to Optimal Scaling in Numerical Radiative Transfer

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.
ABSTRACT We consider a multidimensional polychromatic radiative transfer (RT) problem, accounting for scattering processes in a general form, that is, anisotropic (dipole) scattering with partial frequency redistribution. Given a discrete ordinates (SN$$ {S}_N $$) discretization, we report the corresponding matrix structures, depending on the model and

Algebraic cobordism theory attached to algebraic equivalence

open access: yes, 2013
Based on the algebraic cobordism theory of Levine and Morel, we develop a theory of algebraic cobordism modulo algebraic equivalence. We prove that this theory can reproduce Chow groups modulo algebraic equivalence and the semi-topological K0- groups. We

Generalizing the Gaussian Network Model: Spanning‐Tree Thermodynamics Shows Entropy‐Driven KRAS Activation

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 10, Page 1671-1685, October 2026.
ABSTRACT The GTPase KRAS executes a conformational switch between a GTP‐bound active state and a GDP‐bound inactive state, a process central to oncogenic signaling. However, the structural basis of this switching at the level of residue‐contact organization remains incompletely characterized by traditional binary structural models.

Zeros of polynomials in derivatives of automorphic L$L$‐functions

open access: yesMathematika, Volume 72, Issue 4, October 2026.
Abstract Let Fm$\mathfrak {F}_m$ be the set of all cuspidal automorphic representations of GLm(AQ)$\mathrm{GL}_m(\mathbb {A}_{\mathbb {Q}})$, and let F(s,π)$F(s,\bm {\pi })$ be a polynomial in the derivatives of L$L$‐functions associated with representations π∈⋃m=1∞Fm$\pi \in \bigcup _{m=1}^{\infty } \mathfrak {F}_m$. We establish an asymptotic formula
