This proposal will investigate mathematical issues related to the behaviour of vortex filaments in fluids. This is a topic that has fascinated scholars dating back at least to the days of Leonardo da Vinci, and over the past 60 years, physicists have realized that vortex-like objects are present not only in everyday fluids such as water and air, but also in a wide range of other physical phenomena, ranging from very small scales (quantum mechanical fluids such Bose-Einstein condensates, superconductors, micromagnetic materials) to extremely large scales (hypothetical cosmic strings).

该建议将研究与流体中涡旋细丝的行为有关的数学问题。这个话题至少可以追溯到莱昂纳多·达芬奇（Leonardo da Vinci）时代，在过去的60年中，物理学家意识到，涡流般的物体不仅存在于水和空气等日常液体中，而且还存在在广泛的其他物理现象中，范围从很小的尺度（量子机械液）（例如Bose-Einstein冷凝物，超导体，微磁性材料）到极大的尺度（假设的宇宙字符串）。
