Abstract

In this paper, we introduce a new method of construction called H-super subdivision of graphs and prove that the H-super subdivision of Y -tree Yn+1 (n ≥ 2) is graceful and there by answering the open question posed in 2009 by Arumugam and others [1]. Also we prove that the H-super subdivision of Y -tree is odd and even graceful.
