  • Antimagic Labeling in the Context of Switching of a Vertex 
    Vaidya, S.; Vyas, N. (Annals of Pure and Applied Mathematics, 2012)
    A graph with q edges is called antimagic if its edges can be labeled with 1, 2,…,q such that the sums of the labels of the edges incident to each vertex are distinct. Here we prove that the graphs obtained by switching ...
  • Antimagic Labeling of Some Path and Cycle Related Graphs 
    Vaidya, S.; Vyas, N. (Annals of Pure and Applied Mathematics, 2013)
    An edge labeling of a graph is a bijection from E(G) to the set {1,2,… , |E(G)|}. If for any two distinct vertices u and v, the sum of labels on the edges incident to u is different from the sum of labels on the edges ...
  • E-Cordial Labeling for Cartesian Product of Some Graphs 
    Vaidya, S.; Vyas, N. (Studies in Mathematical Sciences, CSCanada, 2011-11)
    We investigate E-cordial labeling for some cartesian product of graphs. We prove that the graphs Kn × P2 and Pn × P2 are E-cordial for n even while Wn × P2 and K1,n × P2 are E-cordial for n odd.
  • E-Cordial Labeling in the Context of Switching of a Vertex 
    Vaidya, S.; Vyas, N. (International Journal of Advanced Computer and Mathematical Sciences, 2012)
    Let G=(V(G),E(G)) be a graph and f E G : ( ) {0,1} → be a binary edge labeling. Define * f V G : ( ) {0,1} → by * ( ) ( ) ( )( 2) uv E G f v f uv mod ∈ = ∑ . The function f is called E-cordial labeling of G if | ...
  • E-Cordial Labeling of Some Mirror Graphs 
    Vaidya, S.; Vyas, N. (International Journal of Contemporary Advanced Mathematics (IJCM), 2011)
    Let G be a bipartite graph with a partite sets V1 and V2 and G′ be the copy of G with corresponding partite sets V1 ′ and V2 ′ . The mirror graph M(G) of G is obtained from G and G′ by joining each vertex of V1 ...
  • Even Mean Labeling for Path and Bistar related Graphs 
    Vaidya, S.; Vyas, N. (International Journal of Graph Theory(IJOGT), 2013-08)
    An even mean labeling is a variant of mean labeling. Here we investigate even mean labeling for path and bistar related graphs.
  • Product cordial labeling for alternate snake graphs 
    Vaidya, S.; Vyas, N. (Malaya Journal of Matematic (MJM) - An International Journal of mathematical science with computer applications, 2014)
    The product cordial labeling is a variant of cordial labeling. Here we investigate product cordial labeling for alternate triangular snake and alternate quadrilateral snake graphs
  • Product Cordial Labeling for some Bistar related Graphs 
    Vaidya, S.; Vyas, N. (AMO - Advanced Modeling and Optimization, 2014)
    For the graph G = (V (G), E(G)), a function f : V (G) → {0, 1} is called a product cordial labeling of G if the induced edge labeling function defined by the product of end vertex labels be such that the edges with label ...
  • Product Cordial Labeling in the Context of Tensor Product of Graphs 
    Vaidya, S.; Vyas, N. (Journal of Mathematics Research, 2011-08)
    For the graph G1 and G2 the tensor product is denoted by G1(Tp)G2 which is the graph with vertex set V(G1(Tp)G2) = V(G1) × V(G2) and edge set E(G1(Tp)G2) = {(u1, v1), (u2, v2)/u1u2 E(G1) and v1v2 E(G2)}. The graph Pm(Tp)Pn ...
  • Some More Results on Even Mean Labeling 
    Vaidya, S.; vyas, N. (International Journal of Graph Theory(IJOGT), 2013-12)
    A function f: V(G) →{2,4, …, 2|E(G)|} is called an even mean labeling of graph G if it is injective and when each edge e=uv is labeled with average sum of f(u) and f(v) then the resulting edge labels are distinct. Here ...
