Function P-sets is the function form of P-sets, which has the dynamic and law characteristics. Function P-sets is a dynamic law model. Function P-sets is a set pair composed of function internal P-set S and function outer P-set SF, or (S, SF) is function P-sets. P-information law reasoning is obtained by introducing function concept into P-reasoning and improving it. P-information law reasoning is a dynamic information law reasoning, which is presented by using P-sets. P-information law reasoning is composed of internal P-information law reasoning and outer P-information law reasoning. By using the intersection and osmosis of function P-sets and P-information law reasoning, the studies about P-information law intelligent fusion and soft information image intelligent generation are given, which are P-information law reasoning structure, P-information law intelligent fusion and its P-information law reasoning generation, intelligent fusion redundance-deletion and attribute internal-outer fusion characteristic, P-information law intelligent fusion and its expansion-contraction theorem of attribute conjunction normal form, the intelligent P-separation and reduction of P-information law intelligent fusion, split-synthesis of information law and soft information image intelligent generation. Function P-sets is a novel method and theory studying information law fusion.

It has been known that graphs can be used as models in researching scale-free networks, such as hierarchialnetworks and self-similar networks and so on. We study theedge-magic total labellings on splitting and recombining trees. We can adjoin a pair of non-adjacent vertices of a tree having set-ordered graceful labellings to obtain a new graph,  then delete another edge on a cycle of the new graph to form a tree having edge-magic total labellings. And we split a tree M intopieces, and then assemble them on another tree T with |T|<|M| to result a new graph G. After a series of the reducing cycle operations on G, we obtain a tree that admits edge-magic total labellings.

Let G be a planar graph with maximum degree Δ.  The linear 2-arboricity of G is the least integer k such that G can be partitioned into k edge disjoint forests, whose component trees are paths of length at most 2. It is denoted by la2(G). We get that la2(G)≤「Δ／2-+8 if Δ≡0,3(mod 4) and la2(G)≤「Δ／2-+7 if Δ≡1,2(mod 4).

Let G be a graph with vertex set V(G), minimum degree  δ(G) and independent number α(G). Let k≥2 be an integer. A spanning subgraph F of G is called a fractional k-factor if dhG(x)=k for every x∈V(F). A graph G is called a fractional k-uniform graph if for each edge of G, there is a fractional k-factor containing it and another one excluding it. In this paper, we prove that if δ(G)≥k+2 and α(G)≤4k(δ-k-1)(k+1)2, then G is a fractional k-uniform graph.

A proper edge coloring of a graph G is called acyclic if there is no 2-colored cycle in G. The acyclic edge chromatic number of G, denoted by a′(G), is the least number of colors in an acyclic edge coloring of G. It is proved that if a trianglefree toroidal graph G has maximum degree Δ(G), then a′(G)≤Δ(G)+3.

IMTL and its related logic algebras are investigated in depth again and some new useful results are obtained. Firstly, the IMTL*-algebras are introduced by strengthening the conditions of IMTL-algebra, and the existence of IMTL*-algebras is explained by establishing structures of IMTL*-algebra. Secondly, an algebra structure is established that is IMTL-algebra and not IMTL*-algebra, which explains that IMTL*-algebras are truely strengthened form of IMTL-algebras, and  based on IMTL-algebras some equivalent characterization of IMTL*-algebras are given. At last, the pure implication representation of IMTL*-algebras is obtained. The results of this paper are necessary complementarity to the methods and contents of logic algebras.

P-sets(packet sets) is a set pair composed of internal P-set Xand outer P-set XF, while the (σ,τ)-generation of assistant sets of P-sets is also a set pair composed of σ-generation of internal assistant set Aσ(X) and τ-generation of outer assistant set Aτ(XF). Based on the above knowledge, (σ,τ)-expansion model of P-sets is proposed. The relationship theorem between P-sets and its (σ,τ)-expansion is presented. A series of propoties about the (σ,τ)expansion of  P-sets are discussed. (σ,τ)-expansion model of P-sets expands the research field of P-sets.
