On singularities of discontinuous vector fields
Bulletin des Sciences Mathématiques, 2003 The paper is concerned with the classification of typical singularities for a class of four-dimensional discontinuous vector fields. Being inspired by the work of \textit{D. V. Anosov} [Autom. Remote Control 20, 130--143 (1959; Zbl 0093.09204)], the authors consider the semilinear vector field \(L_{a},\) \(a\in\mathbb{R},\) \[ x_{2}\frac{\partial ...

Research on Feature Fusion Method of Mine Microseismic Signal Based on Unsupervised Learning
Shock and Vibration, 2021 The feature extraction of high-precision microseismic signals is an important prerequisite for multicategory recognition of microseismic signals, and it is also an important basis for intelligent sensing modules in smart mines.

Index of singularities of real vector fields on singular hypersurfaces [PDF]
Journal of Singularities, 2014 Gómez-Mont, Seade and Verjovsky introduced an index, now called GSV-index, generalizing the Poincaré-Hopf index to complex vector fields tangent to singular hypersurfaces. The GSV-index extends to the real case. This is a survey paper on the joint research with Gómez-Mont and Giraldo about calculating the GSV-index $\Ind_{V_\pm,0}(X)$ of a real vector ...
