Give three examples of a function f : R\rightarrow R with the following property: for all x in R, f(x + 1) = f(x + 3) For each example of function, justify why it has the required property. Hint: the Which statement is an example of the addition property of equality? a. If...
In this note, a condition (open persistence) is presented under which a (pre)closure operation on submodules (resp. ideals) over rings of global sections over a scheme X can be extended to a (pre)closure operation on sheaves of submodules of a coherent OX-module (resp. sheaves of ideals...

the -subnormal closure of H in G is the subgroup (g∈G∣g∈H(H,H g ) )·" In this paper we prove Doerk's conjecture for groups G∈S, where S is the class of all soluble groups, and is a subgroup-closed saturated formation of finite groups containing the formation of nilpotent gr...
The dual function d(f) of a function f is defined as (d(f))(x1,x2,…,xn)=(non(f))(non(x1),non(x2),…,non(xn)). Moreover, a Boolean function f is called self-dual if and only if d(f)=f. Let D3 denote the set of all self-dual Boolean functions. We extend the con...

We introduce a closure concept for hamiltonicity in the class of {K1,4,K1,4+e}-free graphs, extending the closure for claw-free graphs introduced by Ryjáček (1997) [18]. The closure of a {K1,4,K1,4+e}-free graph G with minimum degree at least 6 is uniquely determined, is a...
