In the study, vortices described by complex numbers are moved from a sphere into a “squeezed” sphere – where the pair of opposite poles become one – called a pinched sphere or concave disk. Vortices on the pinched sphere reflect what is commonly observed in nature. A family of the pinched spheres very well represents the spatial vortices observed daily in gusts of wind. Stock market zigzags constitute an economic vortex – a spiral on the cone whose equivalent is the pinched sphere}, title={Vortices on a pinched sphere}, type={artykuł}, keywords={pinched sphere – concave disk, vortex, complex number}, }
