Invertible matrices over finite additively idempotent semirings
Andreas Kendziorra, Stefan E. Schmidt, Jens Zumbrägel
We investigate invertible matrices over finite additively idempotent semirings. The main result provides a criterion for the invertibility of such matrices. We also give a construc…

Network coding with modular lattices
Andreas Kendziorra, Stefan E. Schmidt
In [1], Kötter and Kschischang presented a new model for error correcting codes in network coding. The alphabet in this model is the subspace lattice of a given vector space, a cod…
