Quantum order from string-net condensations and origin of light and massless fermions
Recently, it was pointed out that quantum orders and the associated projective symmetry groups can produce and protect massless gauge bosons and massless fermions in local bosonic models. In this paper, we demonstrate that a state with such kind of quantum orders can be viewed as a string-net condensed state. The emerging gauge bosons and fermions in local bosonic models can be regarded as a di...
متن کاملComplexity of the Soundness Problem of Bounded Workflow Nets
Classical workflow nets (WF-nets) are an important class of Petri nets that are widely used to model and analyze workflow systems. Soundness is a crucial property that guarantees these systems are deadlock-free and bounded. Aalst et al. proved that the soundness problem is decidable, and proposed (but not proved) that the soundness problem is EXPSPACE-hard. In this paper, we show that the satis...
متن کاملDEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کاملFrequency of illegal abandoned gillnets in the coastal waters of Golestan Province
Gillnets are sometimes abandoned or lost at sea due to sea storms, tearing by a hard object, or the failure of fishermen to find the fishing area. In this study, the data related to the frequency of illegal abandoned fishing nets in Golestan province were collected through field patrols and questionnaire information from spring to winter 2016. 88,465 abandoned fishing nets were collected in the...
متن کاملPetri Net Controlled Grammars: the Case of Special Petri Nets
A Petri net controlled grammar is a context-free grammar equipped with a Petri net, whose transitions are labeled with rules of the grammar or the empty string, and the associated language consists of all terminal strings which can be derived in the grammar and the the sequence of rules in every terminal derivation corresponds to some occurrence sequence of transitions of the Petri net which is...
