In the present paper‎, ‎we propose an iterative algorithm for‎ ‎solving the generalized \$(P,Q)\$-reflexive solution of the quaternion matrix‎ ‎equation \$overset{u}{underset{l=1}{sum}}A_{l}XB_{l}+overset{v} ‎{underset{s=1}{sum}}C_{s}widetilde{X}D_{s}=F\$‎. ‎By this iterative algorithm‎, ‎the solvability of the problem can be determined automatically‎. ‎When the‎ ‎matrix equation is consistent over a generalized \$(P,Q)\$-reflexive matrix \$X\$‎, ‎a‎ ‎generalized \$(P,Q)\$-reflexive solution can be obtained within finite iteration‎ ‎steps in the absence of roundoff errors‎, ‎and the least Frobenius norm‎ ‎generalized \$(P,Q)\$-reflexive solution can be obtained by choosing an‎ ‎appropriate initial iterative matrix‎. ‎Furthermore‎, ‎the optimal approximate‎ ‎generalized \$(P,Q)\$-reflexive solution to a given matrix \$X_{0}\$ can be‎ ‎derived by finding the least Frobenius norm generalized \$(P,Q)\$-reflexive‎ ‎solution of a new corresponding quaternion matrix equation‎. ‎Finally‎, ‎two‎ ‎numerical examples are given to illustrate the efficiency of the proposed methods‎.

In this article‎, ‎we have characterized ideals in \$C(X)\$ in which‎ ‎every ideal is also an ideal (a \$z\$-ideal) of \$C(X)\$‎. ‎Motivated by‎ ‎this characterization‎, ‎we observe that \$C_infty(X)\$ is a regular‎ ‎ring if and only if every open locally compact \$sigma\$-compact‎ ‎subset of \$X\$ is finite‎. ‎Concerning prime ideals‎, ‎it is shown that‎ ‎the sum of every two prime (semiprime) ideals of each ideal in‎ ‎\$C(X)\$ is prime (semiprime) if and only if \$X\$ is an \$F\$-space‎. ‎Concerning maximal ideals of an ideal‎, ‎we generalize the notion of‎ ‎separability to ideals and we have proved the coincidence of‎ ‎separability of an ideal with dense separability of a subspace of‎ ‎\$beta X\$‎. ‎Finally, we have shown that the Goldie dimension of an‎ ‎ideal \$I\$ in \$C(X)\$ coincide with the cellularity of‎ ‎\$XsetminusDelta (I)\$‎.

Let H be a subgroup of a group G. H is said to be S-embedded in G if G has a normal T such that HT is an S-permutable subgroup of G and H ∩ T ≤ H sG, where H denotes the subgroup generated by all those subgroups of H which are S-permutable in G. In this paper, we investigate the inﬂuence of minimal S-embedded subgroups on the structure of ﬁnite groups. We determine the structure the ﬁnite groups with some minimal S-embedded subgroups. We also give some new characterizations of p-nilpotency of ﬁnite groups in terms of S-embedding property. As applications, some previous known results are generalized.

We define a new type of spectrum, called δ-approximate spectrum, of an element a in a complex unital Banach algebra A and show that the δ-approximate spectrum σ_δ (a) of a is compact. The relation between the δ-approximate spectrum and the usual spectrum is investigated. Also an analogue of the classical Gleason-Kahane-Zelazko theorem is established: For each ε>0, there is δ>0 such that if ϕ is a linear functional with ϕ(a)∈σ_δ (a) for all a∈A, then ϕ is ε-almost multiplicative. Finally, we use these ideas to provide a sufficient condition for a δ-almost multiplicative functional to be multiplicative.

‎An  oriented perfect path double cover (OPPDC) of a‎ ‎graph \$G\$ is a collection of directed paths in the symmetric‎ ‎orientation \$G_s\$ of‎ ‎\$G\$ such that‎ ‎each arc‎ ‎of \$G_s\$ lies in exactly one of the paths and each‎ ‎vertex of \$G\$ appears just once as a beginning and just once as an‎ ‎end of a path‎. ‎Maxov{'a} and Ne{v{s}}et{v{r}}il (Discrete‎ ‎Math‎. ‎276 (2004) 287-294) conjectured that every graph except‎ ‎two complete graphs \$K_3\$ and \$K_5\$ has an   OPPDC and they‎ ‎claimed that the minimum degree of the minimal counterexample to‎ ‎this conjecture is at least four‎. ‎In the proof of their claim‎, ‎when a graph is smaller than the minimal counterexample‎, ‎they missed to consider the special cases \$K_3\$ and \$K_5\$‎. ‎In this paper‎, ‎among some‎ ‎other results‎, ‎we present the complete proof for this fact‎. ‎Moreover‎, ‎we prove that the minimal counterexample to this‎ ‎conjecture is \$2\$-connected and \$3\$-edge-connected‎.
