Algorithm to check Maximum Likelihood Estimate Existence for integrated PCA
Dmitri Shmelkin
Being encouraged by [AKRS] that provides an amazing bridge between Statistics and Invariant Theory, and especially by [FM], where quiver semi-invariant techniques apply to verify t…

Some algorithms for semi-invariants of quivers
D. A. Shmelkin
We present some theorems and algorithms for calculating perpendicular categories and locally semi-simple decompositions. We implemented a computer program {\sc TETIVA} based on the…

Locally semi-simple representations of quivers
D. A. Shmelkin
We suggest a geometrical approach to the semi-invariants of quivers based on Luna's slice theorem and the Luna-Richardson theorem. The locally semi-simple representations are defin…
