Web12 de out. de 2014 · A singularity of dimension higher than 2 is called a higher-dimensional singularity. In this section we mostly discuss higher-dimensional singularities. Unless otherwise stated, singularities are always of dimension n ≥ 2. Varieties are all integral algebraic varieties over \mathbb {C} and the singularities considered are on such varieties.

Web26 de nov. de 2004 · For higher order modes the trapping efficiency is better because the gradient of the absolute value of the electric field is higher. However, if the singularities do not coincide, different points of stable trapping might exist in the beam. This will cause an instability in the particle position, which is undesired in high-precision applications. Web302 SCOTT: On the Higher Singularities of Plane Curves. cident tangents occur as the final form of singularities with distinct tangents, involving a number of evanescent loops; the ordinary cusp thus presents itself as a node with an evanescent loop.
