Physical and numerical experiments reveal an unexpected dynamical behaviour of vortex filaments in ideal fluids and superfluids. This unexpected behaviour manifests itself in the appearance of singular shapes, such as corners, in the evolution of the vortex. The proposed research aims to advance our mathematical understanding of the processes leading to formation of such singularities in some well-known models for the evolution of vortex filaments, and in certain intimately related nonlinear Schr\"odinger equations.

物理和数值实验揭示了理想的流体和超流体中涡旋细丝的意外动力学行为。这种意外的行为体现在奇异形状（例如角）的外观中，在涡流的演变中。拟议的研究旨在提高我们对导致涡旋细丝演变的一些奇异性形成过程的过程的数学理解，并在某些密切相关的非线性schr \“ odinger”方程中。
