Dual spaces of geodesic currents
Journal of Topology, Volume 18, Issue 4, December 2025.Abstract Every geodesic current on a hyperbolic surface has an associated dual space. If the current is a lamination, this dual embeds isometrically into a real tree. We show that, in general, the dual space is a Gromov hyperbolic metric tree‐graded space, and express its Gromov hyperbolicity constant in terms of the geodesic current.

Floer theory for the variation operator of an isolated singularity
Journal of Topology, Volume 18, Issue 4, December 2025.Abstract The variation operator in singularity theory maps relative homology cycles to compact cycles in the Milnor fiber using the monodromy. We construct its symplectic analog for an isolated singularity. We define the monodromy Lagrangian Floer cohomology, which provides categorifications of the standard theorems on the variation operator and the ...

Attractors for Differential Equations with Multiple Variable Delays [PDF]
, 2009 We establish some results on the existence of pullback attractors for non-autonomous delay di fferential equations with multiple delays. In particular, we generalise some recent works on the existence of pullback attractors for delay di fferential ...

Pullback Exponential Attractor for Second Order Nonautonomous Lattice System [PDF]
Discrete Dynamics in Nature and Society, 2014 We first present some sufficient conditions for the existence of a pullback exponential attractor for continuous process on the product space of the weighted spaces of infinite sequences. Then we prove the existence and continuity of a pullback exponential attractor for second order lattice system with time-dependent coupled coefficients in the ...

Computer Animation and Virtual Worlds, Volume 36, Issue 6, November/December 2025.Our method generates natural, interactive motion for embodied agents by using overlapping minimum jerk trajectories to control body parts. Trajectory goals are defined in dynamic, target‐relative coordinate systems and can be edited through a no‐code graphical interface.

Pullback Attractors for Nonclassical Diffusion Equations in Noncylindrical Domains [PDF]
International Journal of Mathematics and Mathematical Sciences, 2012 L'existence et l'unicité d'une solution variationnelle sont prouvées pour l' équation de diffusion non-classique non-autonome suivante , dans un domaine non cylindrique avec des conditions limites de Dirichlet homogènes, dans l'hypothèse où les domaines spatiaux sont bornés et augmentent avec le temps.

Growth problems in diagram categories
Bulletin of the London Mathematical Society, Volume 57, Issue 11, Page 3454-3469, November 2025.Abstract In the semisimple case, we derive (asymptotic) formulas for the growth rate of the number of summands in tensor powers of the generating object in diagram/interpolation categories.

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.We investigated desert mammals' utilization of canal wildlife crossing structures (WCSs) in Xinjiang, China, employing COVID‐19 lockdowns as a natural experiment to evaluate anthropogenic disturbance effects. Camera trap data for four focal species revealed shifts in encounter rates, activity patterns, and predator‐prey interactions across pandemic ...

On non-autonomously forced Burgers equation with periodic and Dirichlet boundary conditions
, 2019 We study the non-autonomously forced Burgers equation $$ u_t(x,t) + u(x,t)u_x(x,t) - u_{xx}(x,t) = f(x,t) $$ on the space interval $(0,1)$ with two sets of the boundary conditions: the Dirichlet and periodic ones.

A Setup for Automatic Raman Measurements in High‐Throughput Experimentation
Biotechnology and Bioengineering, Volume 122, Issue 10, Page 2751-2769, October 2025.Record Raman spectra in High‐Throughput Bioprocess Development. Measure eight samples of 50 μL fully automated. ABSTRACT High‐throughput (HT) experimentation is transforming biotechnology by enabling systematic exploration of complex multi‐dimensional experimental conditions. However, current analytical methods are often unable to handle the rapid pace
