ELEGANT TREES
- Ode to GTC
One amongst the several labeling is graceful
Trees are special and conjectured graceful
An impulse from Rosa-Kotzig and Ringel
Oh trees! You are graceful even without label
Without you none could be graceful
As we are here because of your marvel!
Not that we realize you are graceful
We are here to confirm you are indeed graceful!
Given a tree we are sure to show it graceful
But this we fail now to establish in general!
We feel you are indeed graceful
And remain for ever graceful!
We know not why how and where
DST and KREC got labeled
With the assignment GD-GLP rare
Deliberate to find you gracefully labeled!
A humble believer: Suryaprakash Nagoji Rao
*GTC- Graceful tree Conjecture,
DST- Department of Science & Technology; GD-GLP- Group Discussion on Graph Labeling Problems, Venue: KREC, Surathkal: Aug.16-25, 1999.
