We have performed X-ray diffraction experiments on a single crystalline CeCoSi to investigate the unresolved ordered phase below $T_0 \sim 12$ K. discovered that triclinic lattice distortion takes place $T_0$, which is further modified in subsequent antiferromagnetic phase. The structural domains can be selected by applying magnetic field, indicating some electronic ordering exists behind and a...

In this paper, we introduce intuitionistic smooth bitopological spaces and the notions of intuitionistic fuzzy semiinterior and semiclosure. Based on these concepts, the characterizations for the intuitionistic fuzzy pairwise semicontinuous mappings are obtained.

Abstract We consider fragments of uniform reflection for formulas in the analytic hierarchy over theories second order arithmetic. The main result is that any arithmetic theory $T_0$ extending $\mathsf {RCA}_0$ and axiomatizable by a $\Pi ^1_{k+2}$ sentence, $n\geq k+1$ , $$\begin{align*}T_0+ \mathrm{RFN}_{\varPi^1_{n+2}}(T) \ = T_0 + \mathrm{TI}_{\varPi^1_n}(\varepsilon_0), \end{align*}$$ \mat...

Let H be a graph. A graph G is said to be H -free if it contains no subgraph isomorphic to H . A graph G is said to be an H -saturated subgraph of a graph K if G is an H -free subgraph of K with the property that for any edge e∈E(K) \ E(G); G ∪ {e} is not H -free. We present some general results on Ks; t-saturated subgraphs of the complete bipartite graph Km;n and study the problem of 3nding, f...
