Kusner is a geometer, an expert in the analysis of variational problems in low-dimensional geometry and topology, which concerns properties preserved under continuous deformation
such as stretching and bending.
3 Large plastic deformation occurs in the contact zone because the continuous deformation
and flow of mental occurs along rolling direction and spread direction.
The formation of nanosized fibers is an overall result of production of microsized micelles of thermoplastic polymers in cellulose acetate butyrate and continuous deformation
, elongation, and coalescence of the micelles to nanofibers in and at the outlet of a die before the composite fiber is completely solidified .
Creates smooth, continuous deformation
of the input model
It is an area of mathematics concerned with the properties of space that are preserved under continuous deformations
including stretching and bending, but not tearing or gluing.
