How Not to Characterize Planar-emulable Graphs
Markus Chimani, Martin Derka, Petr Hliněný +1
We investigate the question of which graphs have planar emulators (a locally-surjective homomorphism from some finite planar graph) -- a problem raised already in Fellows' thesis (…
Covariant Lagrange multiplier constrained higher derivative gravity with scalar projectors
Josef Kluson, Shin'ichi Nojiri, Sergei D. Odintsov
We formulate higher derivative gravity with Lagrange multiplier constraint and scalar projectors. Its gauge-fixed formulation as well as vector fields formulation is developed and…
Approximating the Termination Value of One-Counter MDPs and Stochastic Games
Tomáš Brázdil, Václav Brožek, Kousha Etessami +1
One-counter MDPs (OC-MDPs) and one-counter simple stochastic games (OC-SSGs) are 1-player, and 2-player turn-based zero-sum, stochastic games played on the transition graph of clas…
Spin-orbital resonating valence bond liquid on a triangular lattice: Evidence from finite-cluster diagonalization
Jiří Chaloupka, Andrzej M. Oleś
We investigate the ground state of the spin-orbital model for triply degenerate orbitals on a triangular lattice which unifies intrinsic frustration of spin and orbi…
Purification of genuine multipartite entanglement
Marcus Huber, Martin Plesch
In tasks, where multipartite entanglement plays a central role, state purification is, due to inevitable noise, a crucial part of the procedure. We consider a scenario exploiting t…
SIM(2) and supergraphs
Stanislav Petráš, Rikard von Unge, Jiří Vohánka
We construct Feynman rules and Supergraphs in SIM(2) superspace. To test our methods we perform a one-loop calculation of the effective action of the SIM(2) supersymmetric Wess-Zum…
