Complexity Properties of Critical Sets of Arguments [PDF]
, 2014 In an abstract argumentation framework, there are often multiple plausible ways to evaluate (or label) the status of each argument as accepted, rejected, or undecided. But often there exists a critical set of arguments whose status is sufficient to determine uniquely the status of every other argument.

Critical properties of superconducting Ba1−xKxFe2As2 [PDF]
Physica C: Superconductivity, 2010 Magnetisation and magnetoresistance measurements have been carried out on superconducting Ba1-xKxFe2As2 samples with x=0.40 and 0.50. From low field magnetization data carried out at different temperatures below TC, HC1 has been extracted. The plot of HC1 versus temperature shows an anomalous increase at low temperatures.

Critical properties of bipartite permutation graphs
Journal of Graph Theory, 2023 AbstractThe class of bipartite permutation graphs enjoys many nice and important properties. In particular, this class is critically important in the study of clique‐ and rank‐width of graphs, because it is one of the minimal hereditary classes of graphs of unbounded clique‐ and rank‐width.

Critical Properties of the Kitaev-Heisenberg Model
Physical Review Letters, 2012 We study critical properties of the Kitaev-Heisenberg model on the honeycomb lattice at finite temperatures which might describe the physics of the quasi two-dimensional compounds, Na$_2$IrO$_3$ and Li$_2$IrO$_3$. The model undergoes two phase transitions as a function of temperature.

Critical Properties of the Mixed Ising Ferromagnet
Journal of Physics C: Solid State Physics, 1980 A real-space rescaling method is applied to the mixed-bond, spin--½, Ising model. The system comprises bonds JA, JB with probability p, 1-p respectively. We restrict our attention to the mixed ferromagnet for which JA, JB > 0. Critical curves, Tc versus p, can be obtained for all α ≡ JB/JA and we present results for the square lattice for α = 1,2,5,10,∞
