Symplectic and Poisson derived geometry and deformation quantization [PDF]
Algebraic Geometry, 2016 We review recent results and ongoing investigations of the symplectic and Poisson geometry of derived moduli spaces, and describe applications to deformation quantization of such spaces.

The 2‐divisibility of divisors on K3 surfaces in characteristic 2
Mathematische Nachrichten, EarlyView.Abstract We show that K3 surfaces in characteristic 2 can admit sets of n$n$ disjoint smooth rational curves whose sum is divisible by 2 in the Picard group, for each n=8,12,16,20$n=8,12,16,20$. More precisely, all values occur on supersingular K3 surfaces, with exceptions only at Artin invariants 1 and 10, while on K3 surfaces of finite height, only n=

On the hyperbolic symplectic geometry
Journal of Combinatorial Theory, Series A, 2004 AbstractThe present article provides a new characterization of the geometry on the points and hyperbolic lines of a non-degenerate symplectic polar space. This characterization is accomplished by studying the family of subspaces obtained when considering the polars of all hyperbolic lines.

Multiphysics Simulation Methods in Computer Graphics
Computer Graphics Forum, EarlyView.Abstract Physics simulation is a cornerstone of many computer graphics applications, ranging from video games and virtual reality to visual effects and computational design. The number of techniques for physically‐based modeling and animation has thus skyrocketed over the past few decades, facilitating the simulation of a wide variety of materials and ...

Gear fault diagnosis based on SGMD noise reduction and CNN
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2022 Gear vibration fault signals are non-stationary and nonlinear, so it is very difficult to accurately extract the fault characteristics for diagnosis. As symplectic geometry mode decomposition (SGMD) has shown excellent decomposition performance and noise

Hyper-symplectic structures on integrable systems
, 2003 We prove that an integrable system over a symplectic manifold, whose symplectic form is covariantly constant w.r.t. the Gauss-Manin connection, carries a natural hyper-symplectic structure.

Toric degenerations and symplectic geometry of smooth projective varieties [PDF]
Journal of the London Mathematical Society, 2015 Let X be an n ‐dimensional smooth complex projective variety embedded in CPN . We construct a smooth family X over C with an embedding in CPN×C such that its generic fiber is X and its special fiber is the torus (C∗)n sitting in CPN via a monomial ...

Modal identification of wind turbine tower based on optimal fractional order statistical moments
Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 13, Page 1754-1768, 19 May 2025.Abstract In vibration testing of civil engineering structures, the first two vibration modes are crucial in representing the global dynamic behavior of the structure measured. In the present study, a comprehensive method is proposed to identify the first two vibration modes of wind turbine towers, which is based on the analysis of fractional order ...

Symplectic geometry of unbiasedness and critical points of a potential [PDF]
, 2015 The goal of these notes is to show that the classification problem of algebraically unbiased system of projectors has an interpretation in symplectic geometry. This leads us to a description of the moduli space of algebraically unbiased bases as critical
