Gigla Janashia (Georgian: გიგლა ჯანაშია; 27 September 1927, in Tbilisi – 27 April 2005) was a Georgian mathematician. He was the key author of Janashia-Lagvilava matrix spectral factorization (MSF) method.[1] The major recognition of his achievements came after Janashia’s death, when the USPTO granted the patent to this method and its applications, which is extremely rare for pure mathematicians.
