Abstract :
A mapping f : V (G) ! f0; 1; 2g is called 3-product cor-
dial labeling if jvf (i)vf (j)j 1 and jef (i)ef (j)j 1
for any i; j 2 f0; 1; 2g, where vf (i) denotes the number of
vertices labeled with i; ef (i) denotes the number of edges
xy with f(x)f(y) i(mod 3). A graph with 3-product
cordial labeling is called 3-product cordial graph. In this
paper we establish that vertex switching of wheel,gear
graph and degree splitting of bistar are 3-product cordial
graphs.
