چکیده    Consider a simple connected graph g with the vertex set v(g). the eccentric and total connectivity indices of g are defined as ?^c (g)=?_(v?v(g))???ec?_g (v) ?deg?_g (v)? and ec(g)=?_(v?v(g))???ec?_g (v) ?, respectively. here, ?deg?_g (v) denotes the degree of a vertex v and ?ec?_g (v) is its eccentricity. in this paper, these two indices are calculated for a given arbitrary caterpillar.
