Bifibrations, in symplectic geometry called also dual pairs, play a relevant role in the theory of superintegrable Hamiltonian systems. We prove the existence of an analogous bifibrated geometry in dynamical systems with a symmetry group such that the ...

针对传统辛几何模态分解(symplectic geometry mode decomposition, 简称SGMD)方法因嵌入维数选择依靠经验公式,导致出现信号模态混叠和过度分解的问题,提出了一种改进的辛几何模态分解(improved symplectic geometry mode decomposition, 简称ISGMD)方法。首先,通过计算原始信号的功率谱密度得到最大主峰的频率并设定嵌入维数区间,根据峭度准则筛选分解后的辛几何分量(symplectic geometry component,

Symplectic geometry of conical symplectic resolutions
Ever since Kronheimer's celebrated hyperkähler construction of gravitational instantons thirty years ago, many similar constructions have appeared in the mathematical literature, eventually producing a vast class of holomorphic symplectic manifolds nowadays called Conical Symplectic Resolutions (CSRs).

The current methods for early fault diagnosis of rolling bearing have some flaws, such as poor fault feature information and insufficient fault feature extraction capability, which makes it challenging to guarantee fault diagnosis accuracy.

$\mathbf {5 \times 5}$ -graded Lie algebras, cubic norm structures and quadrangular algebras
We study simple Lie algebras generated by extremal elements, over arbitrary fields of arbitrary characteristic. We show the following: (1) If the extremal geometry contains lines, then the Lie algebra admits a $5 \times 5$ -grading that can be ...

Symplectic Geometry and Circuit Quantization
Circuit quantization is an extraordinarily successful theory that describes the behavior of quantum circuits with high precision. The most widely used approach of circuit quantization relies on introducing a classical Lagrangian whose degrees of freedom are either magnetic fluxes or electric charges in the circuit.
