LINGPING ZHONG1,*
The Harmonic index of a graph G is defined as the sum of the weights2 d(u) d(v) of all edges uv of G, where d(u) denotes the degree of a vertex u in G. In this paper, we determine molecular trees with minimum, second-minimum, third-minimum, maximum, second-maximum and third-maximum Harmonic indices..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
