Heat equation and ergodic theorems for Riemann surface laminations [PDF]

open access: yes, 2010
We study the dynamics of possibly singular foliations by Riemann surfaces. The main examples are holomorphic foliations by Riemann surfaces in projective varieties.

Strongly Nonlinear Transverse Perturbations in Phononic Crystals

open access: yesAbstract and Applied Analysis, 2014
The dynamics of the surface heterogeneities formation in low-dimensional phononic crystals is studied. It is shown that phononic transverse perturbations in this medium are highly nonlinear. They can be described with the help of the Riemann wave and may

Punctures from Probe M5-Branes and N=1 Superconformal Field Theories [PDF]

open access: yes, 2013
We study probe M5-branes in N=1 AdS5 solutions of M-theory that arise from M5-branes wrapped on a Riemann surface. Using the BPS condition from kappa-symmetry, we classify supersymmetric probe M5-branes that extend along all of AdS5 and intersect the ...

Hyperbolic geometry and closed bosonic string field theory. Part I. The string vertices via hyperbolic Riemann surfaces

open access: yesJournal of High Energy Physics, 2019
The main geometric ingredient of the closed string field theory are the string vertices, the collections of string diagrams describing the elementary closed string interactions, satisfying the quantum Batalian-Vilkovisky master equation.

Riemann-Hilbert problem associated to Frobenius manifold structures on Hurwitz spaces: irregular singularity

open access: yes, 2008
Solutions to the Riemann-Hilbert problems with irregular singularities naturally associated to semisimple Frobenius manifold structures on Hurwitz spaces (moduli spaces of meromorphic functions on Riemann surfaces) are constructed.

Self-Dual Strings and Stability of BPS States in N=2 SU(2) Gauge Theories [PDF]

open access: yes, 1996
We show how BPS states of supersymmetric SU(2) Yang-Mills with matter -both massless and massive- are described as self-dual strings on a Riemann surface. This connection enables us to prove the stability and the strong coupling behaviour of these states.

Stieltjes–Bethe equations in higher genus and branched coverings with even ramifications

open access: yesNuclear Physics B, 2018
We describe projective structures on a Riemann surface corresponding to monodromy groups which have trivial SL(2) monodromies around singularities and trivial PSL(2) monodromies along homologically non-trivial loops on a Riemann surface.

Active Force Dynamics in Red Blood Cells Under Non‐Invasive Optical Tweezers

open access: yesAdvanced Science, EarlyView.
A non‐invasive method combines low‐power optical tweezers with high‐speed microscopy to simultaneously monitor local membrane forces and displacements in single human red blood cells. This dual‐channel approach reveals a mechano‐dynamic signature that correlates the cell's metabolic state with its mechanical activity. This energetic framework serves as

F-Theory and N=1 SCFTs in Four Dimensions

open access: yes, 2016
Using the F-theory realization, we identify a subclass of 6d (1,0) SCFTs whose compactification on a Riemann surface leads to N = 1 4d SCFTs where the moduli space of the Riemann surface is part of the moduli space of the theory.

Strong asymptotics for Cauchy biorthogonal polynomials with application to the Cauchy two--matrix model [PDF]

open access: yes, 2012
We apply the nonlinear steepest descent method to a class of 3x3 Riemann-Hilbert problems introduced in connection with the Cauchy two-matrix random model.
