Mathematical results on harmonic polynomials

Walter Carballosa, Juan E. Nápoles, J. M Rodríguez, Omar Rosario, J. M. Sigarreta

摘要:

几年前,为了更好地理解调和拓扑指数,引入了调和多项式;例如,它允许获得图的主积的调和指数的界。在这里,我们得到了这个多项式的几个性质,我们证明了图的几个性质可以从他们的调和多项式推出。此外,我们表明,两个图具有相同的调和多项式是相似的。

英文摘要:

Some years ago, the harmonic polynomial was introduced in order to understand better the harmonic topological index; for instance, it allows to obtain bounds of the harmonic index of the main products of graphs. Here, we obtain several properties of this polynomial, and we prove that several properties of graphs can be deduced from their harmonic polynomials. Also, we show that two graphs with the same harmonic polynomial have to be similar.
