Realization of compact Lie algebras in K\"ahler manifolds

open access: yes, 1994
The Berezin quantization on a simply connected homogeneous K\"{a}hler manifold, which is considered as a phase space for a dynamical system, enables a description of the quantal system in a (finite-dimensional) Hilbert space of holomorphic functions ...

Some identities of degenerate Fubini polynomials arising from differential equations

open access: yesJournal of Nonlinear Sciences and Applications, 2018
Summary: Recently, \textit{T. Kim} et al. have studied degenerate Fubini polynomials in [ibid. 9, No. 5, 2857--2864 (2016; Zbl 1338.11035)]. \textit{G.-W. Jang} and \textit{T. Kim} presented some identities of Fubini polynomials arising from differential equations in [Adv. Stud. Contemp. Math., Kyungshang 28, No. 1, 149--160 (2018; Zbl 1424.93094)]. In

Debiasing piecewise deterministic Markov process samplers using couplings

open access: yesScandinavian Journal of Statistics, Volume 52, Issue 4, Page 1932-1974, December 2025.
Abstract Monte Carlo methods—such as Markov chain Monte Carlo (MCMC) and piecewise deterministic Markov process (PDMP) samplers—provide asymptotically exact estimators of expectations under a target distribution. There is growing interest in alternatives to this asymptotic regime, in particular in constructing estimators that are exact in the limit of ...

Boundary conditions and universal finite‐size scaling for the hierarchical |φ|4$|\varphi |^4$ model in dimensions 4 and higher

open access: yesCommunications on Pure and Applied Mathematics, Volume 78, Issue 10, Page 2001-2118, October 2025.
Abstract We analyse and clarify the finite‐size scaling of the weakly‐coupled hierarchical n$n$‐component |φ|4$|\varphi |^4$ model for all integers n≥1$n \ge 1$ in all dimensions d≥4$d\ge 4$, for both free and periodic boundary conditions. For d>4$d>4$, we prove that for a volume of size Rd$R^{d}$ with periodic boundary conditions the infinite‐volume ...

Correlations of the squares of the Riemann zeta function on the critical line

open access: yesJournal of the London Mathematical Society, Volume 112, Issue 3, September 2025.
Abstract We compute the average of a product of two shifted squares of the Riemann zeta function on the critical line with shifts up to size T3/2−ε$T^{3/2-\varepsilon }$. We give an explicit expression for such an average and derive an approximate spectral expansion for the error term similar to Motohashi's.

Quantum states to brane geometries via fuzzy moduli spaces of giant gravitons

open access: yes, 2012
Eighth-BPS local operators in N=4 SYM are dual to quantum states arising from the quantization of a moduli space of giant gravitons in AdS5xS5. Earlier results on the quantization of this moduli space give a Hilbert space of multiple harmonic oscillators

Regularity of the SLE4 uniformizing map and the SLE8 trace

open access: yesProceedings of the London Mathematical Society, Volume 131, Issue 2, August 2025.
Abstract We show that the modulus of continuity of the SLE4${\rm SLE}_4$ uniformizing map is given by (logδ−1)−1/3+o(1)$(\log \delta ^{-1})^{-1/3+o(1)}$ as δ→0$\delta \rightarrow 0$. As a consequence of our analysis, we show that the Jones–Smirnov conditions for conformal removability (with quasihyperbolic geodesics) do not hold for SLE4${\rm SLE}_4 ...

Mixed orthogonality graphs for continuous‐time state space models and orthogonal projections

open access: yesJournal of Time Series Analysis, Volume 46, Issue 4, Page 692-726, July 2025.
In this article, we derive (local) orthogonality graphs for the popular continuous‐time state space models, including in particular multivariate continuous‐time ARMA (MCARMA) processes. In these (local) orthogonality graphs, vertices represent the components of the process, directed edges between the vertices indicate causal influences and undirected ...
