DESCRIPTION:My focus of the talk will be the introduction to t
he integral reduction program Kira. The new additi
on to the palate of tools in Kira is the applicati
on of the finite field methods to reconstruct the
coefficients in Feynman integral reductions to the
master integrals. I will go through examples and
help to understand how to use Kira to optimize all
reduction steps. Also I will discuss different ap
proaches to finish a reduction by using pure analy
tic\, finite field or hybrid methods. At the end I
would like to advertise the paper arXiv:1912.0929
4v3 and discuss how the future of Feynman integral
s reduction may look like.
