Lokesha 1 Sushmitha Jain sushmithajain9@gmail.com 1 T. Deepika 1 Department of Studies in Mathematics, Vijayanagara Sri Krishnadevaraya University, Ballari, India Due to the presence of multicenter bonds and their novel electronic properties, boron nanotubes are attractive. The tri-hexagonal boron nanotubes are build up from triangles and hexagons. It is useful to the QSPR/QSAR studies. Topological indices are classified in different forms such as, degree based topological indices, distance based topological indices and counting related topological indices etc. Here, we concentrated the reckoning of topological indices such as first zagreb, second zagreb, modified second zagreb index, generalized randic index, symmetric division degree index for the tri-hexagonal boron nanotube. Also, established their M-polynomials and using maple software plotted the 3D structure. http://pubs.sciepub.com/tjant/5/6/1/tjant-5-6-1.pdf Tri-hexagonal boron nanotube topological indices M-polynomials
