On the Forsythe conjecture
Vance Faber, Jörg Liesen, Petr Tichý
Forsythe formulated a conjecture about the asymptotic behavior of the restarted conjugate gradient method in 1968. We translate several of his results into modern terms, and genera…
Centrality of nodes in Federated Byzantine Agreement Systems
André Gaul, Jörg Liesen
The federated Byzantine agreement system (FBAS) is a consensus model introduced by Mazières in 2016 where the participating nodes conceptually form a network, with links between th…
Analysis of the multiplicative Schwarz method for matrices with a special block structure
Carlos Echeverría, Jörg Liesen, Petr Tichý
We analyze the convergence of the (algebraic) multiplicative Schwarz method applied to linear algebraic systems with matrices having a special block structure that arises, for exam…
Mathematical Analysis and Algorithms for Federated Byzantine Agreement Systems
André Gaul, Ismail Khoffi, Jörg Liesen +1
We give an introduction to federated Byzantine agreement systems (FBAS) with many examples ranging from small "academic" cases to the current Stellar network. We then analyze the m…
