An asymptotic method of factorization of a class of matrix functions
Gennady Mishuris, Sergei Rogosin · Proceedings of the Royal Society A Mathematical Physical and Engineering Sciences · 2014
A novel method of asymptotic factorization of n × n matrix functions is proposed. The considered class of matrices is motivated by certain problems originated from the elasticity theory. An example is constructed to illustrate efficiency of the proposed procedure. The quality of approximation and the role of the chosen small parameter are discussed.
