We analyze whether random network formation processes, such as preferential attachment, can emerge the outcome of strategic behaviour. represent an extensive game in which players sequentially form links they enter network. In this setting, we investigate under conditions subgame perfect equilibria are observationally equivalent with process. put forward two structural that necessary respect. F...

The representation of large subsets of the World Wide Web in the form of a directed graph has been extensively used to analyze structure, behavior, and evolution of those so-called Web graphs. However, interesting Web graphs are very large and their classical representations do not fit into the main memory of typical computers, whereas the required graph algorithms perform inefficiently on seco...

We introduce a sequent calculus for bilattice-based annotated logic (BAL). We show that this logic can be syntactically and semantically translated into a fragment MSL∗ of conventional many-sorted logic MSL. We show deductive equivalence of sequent calculus for BAL and sequent calculus for MSL∗.

Correlations between BAL QSO intrinsic properties and polarization have been searched for. Some results are summarized here, providing possible constraints on BAL outflow models.

The Sloan Digital Sky Survey has discovered a population of broad absorption line quasars with various extreme properties. Many show absorption from metastable states of Fe ii with varying excitations; several objects are almost completely absorbed bluewards of Mg ii; at 1

We investigate gravitational lens models for the quadruply-lensed Cloverleaf BAL QSO H1413+1143 based on the HST WFPC/WFPC2 astrometric and photometric data of the system by Turnshek et al. and the HST NICMOS-2 data by Falco et al. The accurate image positions and the dust-extinction-corrected relative amplifications, along with a possible detection of the lensing galaxy in the infrared, permit...

Abstract In this note, we apply weighted hierarchical games of cooperative game theory to the problem optimal firm size firm. particular, analyze influence production technology on Our note enhances previous approaches using a permission structure with equally strong relationships between predecessor and direct successors.
