Energy of a molecule plays an important role in physics, chemistry and biology. In mathematics, the concept of energy is used in graph theory to help other subjects such as chemistry and physics. In graph theory, nullity is the number of zeros extracted from the characteristic polynomials obtained from the adjacency matrix, and inertia represents the positive and negative eigenvalues of the adjacency matrix. Energy is the sum of the absolute eigenvalues of its adjacency matrix. In this study, the inertia, nullity and signature of the aforementioned structures have been discussed.

亚苯基和蒽的能量，惯性和无效性的理论研究

分子的能量在物理，化学和生物学中起着重要的作用。在数学中，图论使用能量的概念来帮助其他学科，例如化学和物理。在图论中，零值是从从邻接矩阵获得的特征多项式中提取的零的数量，而惯性表示邻接矩阵的正和负特征值。能量是其邻接矩阵的绝对特征值之和。在这项研究中，已经讨论了上述结构的惯性，无效性和特征。
