چکیده

Let e be an edge of a g connecting the vertices u and v. define two setsn1 (e ? g)and n2(e?g) asn1(e ? g)= {x?v(g)? d(x,u)? d(x,v)}andn2(e ? g)= {x?v(g)? d(x,v)? d(x,u) }.the number of elements ofn1(e ? g) and n2(e ? g) are denoted byn1(e ? g) andn2(e ? g) respectively. the szeged index of the graph g is defined assz(g) . in this paper we compute the szeged index of a 4,4?-bipyridinium dendrimer.
