LIHUI YANG1, HONGBO HUA2,*
The Harmonic index of a graph G is defined as uv E G G G d u d vH G , where d (v) G is the degree of vertex v in G. In this paper, we first report some further mathematical properties of Harmonic index for general connected graphs. Then we give explicit computing formulae for Harmonic index of nanocones and triangular benzenoid graphs, respectively..

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.
