چکیده
There is no one to one 1-Lipschitz function from S2 to the interval [0,1] because of 1.2. Is there finite to one 1-Lipschitz function from S2 to the interval [0,1]? Is there countable to one 1-Lipschitz fuction from S2 to the interval [0,1]? The answers are no for both questions becase of 5.3. In this paper, I define a family of new metrics on the Euclidean 2-sphere of radius r in which the distances between antipodal points are closer than in the standard Euclidean metric. Note that the distances between two points which are near antipodal should be changed, too to satisfy triangle inequalities of new metrics. Consider all possible isometric embeddings of any family of Euclidean 2-spheres with not necessarily different radii into B3 = {(x, y, z) ∈ R | x2+y2+z2 ≤ 1} up to rotations. In this paper I restrict my interest on the isometric embeddings of Euclidean 2-spheres which cover B3 and in which any two point in B3 can be connected with finite number of embedded 2-spheres. Therefore I get a family of path connected metrics on B3 in cannonical way. I change metrics of embedded 2-sphere from the standard Euclidean metric to the new metrics which I already defined above in arbitrary way. Therefore I get a family of pseudo metrics on B3 in cannonical way. Although I study on these pseudo metrics on B3 in this paper, they can be cannonically generalized to a bigger family of pseudo metrics on B3. I define the bigger family of pseudo metrics and the quantum structure in the last section for futher study.

Let B be the closed unit ball in R and S its boundary. We define a family of pseudo metrics on B. As an application, we prove that for any countable-to-one function f : S → [0, a], the set NMnf = {x ∈ S 2 | there exists y ∈ S2 such that f(x)−f(y) > ndE(x, y)} is uncountable for all n ∈ N, where dE is the Euclidean metric on R . 2000 Mathematics Subject Classification ; 57N05, 57M40 1 The family...

We define a family of pseudo metrics on B and study elementary properties of the associated metric spaces. As an application we prove that, for any a > 0 and for any countable-to-one function f from (S, dE) to [0, a], the set NMnf = {x ∈ S 2 | ∃y ∈ S such that f(x)− f(y) > ndE(x, y)} is uncountable for all n ∈ N, where dE is the standard Euclidean metric on S = { (x, y, z) ∈ R | x + y + z = 1 }

متن کاملStudies on Adsorption of Some Organic Dyes from Aqueous Solution onto Graphene Nanosheets
Graphene, a new member of the carbon family, was used as an adsorbent due to its exceptional capability to remove Rhodamine B (RB) and Malachite Green (MG), two organic dyes, from aqueous solutions. Adsorption kinetics of RB and MG onto graphene and adsorption capacity of the adsorbent were studied. Also the effects of parameters, including pH, contact time, temperature, and adsorbent dosag...
متن کاملThe Existence Theorem for Contractive Mappings on $wt$-distance in $b$-metric Spaces Endowed with a Graph and its Application
In this paper, we study the existence and uniqueness of fixed points for mappings with respect to a $wt$-distance in $b$-metric spaces endowed with a graph. Our results are significant, since we replace the condition of continuity of mapping with the condition of orbitally $G$-continuity of mapping and we consider $b$-metric spaces with graph instead of $b$-metric spaces, under which can be gen...
