A Total Mean Cordial labeling of a graph G = (V,E) is a mapping f : V (G) → {0, 1, 2} such that f(xy) = ⌈

A graph G is said to have totally magic cordial(TMC) labeling with constant C if there exists a mapping f : V (G) ∪ E(G) → {0, 1} such that f(a) + f(b) + f(ab) ≡ C (mod 2) for all ab ∈ E(G) and |nf (0)− nf (1)| ≤ 1, where nf (i)(i = 0, 1) is the sum of the number of vertices and edges with label i. In this paper, we investigate some new families of graphs that admit totally magic cordial labeli...

let z2 = {0, 1} and g = (v ,e) be a graph. a labeling f : v → z2 induces an edge labeling f* : e →z2 defined by f*(uv) = f(u).f (v). for i ε z2 let vf (i) = v(i) = card{v ε v : f(v) = i} and ef (i) = e(i) = {e ε e : f*(e) = i}. a labeling f is said to be vertex-friendly if | v(0) − v(1) |≤ 1. the vertex balance index set is defined by {| ef (0) − ef (1) | : f is vertex-friendly}. in this paper ...

Alcohol intoxication is a potentially under-recognised precipitant of Brugada syndrome. Higher pre-cordial electrocardiogram lead placement increases sensitivity of detecting the Brugada pattern.

In this paper we discuss cordial labeling in context of barycentric subdivision of shell graph, complete bipartite graph Kn,n and wheel graph. AMS subject classification: 05C78.

The organs of government are institution set up by the state for will states to be formulated, and achieved. mode operation these varies differs across different system government. In Nigeria, presidential federal is adopted. Separation powers checks balances effectively operated which can either cordial or conflictual. It in lieu this that article focuses on examining pattern nature relationsh...
