Myhill-Nerode methods for hypergraphs
René van Bevern, Rodney G. Downey, Michael R. Fellows +2
We give an analog of the Myhill-Nerode methods from formal language theory for hypergraphs and use it to derive the following results for two NP-hard hypergraph problems: * We prov…
Blackbody radiation shift of B clock transition
Yongjun Cheng, J. Mitroy
A calculation of the blackbody radiation shift of the B clock transition is performed. The polarizabilities of the B S, P, and P$^o…
Minimizing the regularity of maximal regular antichains of 2- and 3-sets
Thomas Kalinowski, Uwe Leck, Christian Reiher +1
Let be a natural number. We study the problem to find the smallest such that there is a family of 2-subsets and 3-subsets of wi…
Maximal antichains of minimum size
Thomas Kalinowski, Uwe Leck, Ian T. Roberts
Let be a natural number, and let be a set . We study the problem to find the smallest possible size of a maximal family $\mathcal{A}…
Computational investigation of static multipole polarizabilities and sum rules for ground-state hydrogen-like ions
Li-Yan Tang, Yong-Hui Zhang, Xian-Zhou Zhang +2
High precision multipole polarizabilities, for of the ground state of the hydrogen isoelectronic series are obtained from the Dirac equation using the…
Positron attachment to the He doubly excited states
M. W. J. Bromley, J. Mitroy, K. Varga
The projection method is used to demonstrate the existence of positron attachment to three doubly excited states of helium. The e^+He(2s^2 1Se), e^+He(3s^2 1Se), and the e^+He(2s2p…
