Topology and signature changes in braneworlds [PDF]

open access: greenClassical and Quantum Gravity, 2004
It has been believed that topology and signature change of the universe can only happen accompanied by singularities, in classical, or instantons, in quantum, gravity.

Adapted topologies and higher rank signatures [PDF]

open access: hybridThe Annals of Applied Probability, 2023
The topology of weak convergence does not account for the growth of information over time that is captured in the filtration of an adapted stochastic process. For example, two adapted stochastic processes can have very similar laws but give completely different results in applications such as optimal stopping, queuing theory, or stochastic programming.

Signature of topology via heat transfer analysis in the Su–Schrieffer–Heeger (SSH) model [PDF]

open access: goldNew Journal of Physics, 2023
In this work, we explore how thermodynamics can be a potential tool for identifying the topological phase transition. Specifically, we focus on a one-dimensional Su–Schrieffer–Heeger (SSH) chain sandwiched between two fermionic baths.

Circuit topology analysis of cellular genome reveals signature motifs, conformational heterogeneity, and scaling [PDF]

open access: goldiScience, 2022
Summary: Reciprocal regulation of genome topology and function is a fundamental and enduring puzzle in biology. The wealth of data provided by Hi-C libraries offers the opportunity to unravel this relationship.

Fermi surface topology and signature of surface Dirac nodes in LaBi

open access: yesScientific Reports, 2017
Novel topological state of matter is one of the rapidly growing fields in condensed matter physics research in recent times. While these materials are fascinating from the aspect of fundamental physics of relativistic particles, their exotic transport ...

Dynamical determination of the metric signature in spacetime of non-trivial topology [PDF]

open access: green, 1994
The formalism of Greensite for treating the spacetime signature as a dynamical degree of freedom induced by quantum fields is considered for spacetimes with nontrivial topology of the kind ${\bf R}^{D-1} \times {\bf T}^1$, for varying $D$.

Signatures in algebra, topology and dynamics

open access: bronzeEnsaios Matemáticos, 2016
We survey the 19th century development of the signature of a quadratic form, and the applications in the 20th and 21st century to the topology of manifolds and dynamical systems. Version 2 is an expanded and corrected version of Version 1, including an Appendix by the second named author "Algebraic L-theory of rings with involution and the localization

Persistent geometry-topology descriptor for porous structure retrieval based on Heat Kernel Signature

open access: goldGraphical Models
Porous structures are essential in a variety of fields such as materials science and chemistry. To retrieve porous materials efficiently, novel descriptors are required to quantify the geometric and topological features. In this paper, we present a novel

Topological isoconductance signatures in Majorana nanowires [PDF]

open access: yesScientific Reports, 2021
AbstractWe consider transport properties of a hybrid device composed by a quantum dot placed between normal and superconducting reservoirs, and coupled to a Majorana nanowire: a topological superconducting segment hosting Majorana bound states (MBSs) at the opposite ends.

Signatures of Topological Branched Covers [PDF]

open access: yesInternational Mathematics Research Notices, 2020
Abstract Let $X^4$ and $Y^4$ be smooth manifolds and $f: X\to Y$ a branched cover with branching set $B$. Classically, if $B$ is smoothly embedded in $Y$, the signature $\sigma (X)$ can be computed from data about $Y$, $B$ and the local degrees of $f$. When $f$ is an irregular dihedral cover and $B\subset Y$ smoothly embedded away from a
