On friendly index sets and product-cordial index sets of gear graphs

Let G = (V,E) be a simple connected graph. A vertex labeling of f:V→{0,1} of G induces two edge labelings f+, f*:E→{0,1} defined by f+(xy)x =x f(x)+f(y)(mod2) and f*(xy)x =x f(x)f(y) for each edge xy ε E. For iε{0,1}, let vf(i)x =x |{vεV:f(v)x =x i}|, ef+(i)x =x |{eεE:f+(e)x =x i}| and ef*(i)x =x |e...
