One Graphic Model Of Trigonometry Debt

Trigonometry debt is a perplexing debt relation inwhich enterprises default debts with each other. Debtproblem is usually resulted from the capital gap causedby insufficient capacity to pay when supply can’t meet thedemand. The primary and direct cause of trigonometry debtsis more or less like the one of debt problem. Trigonometry debtis an obvious problem in current economy, seriouslyundermining the production and operation of enterprises and thedevelopment of the national economy.This paper proceed from actual conditions of Trigonometry debt，studied upon the views of graphic theory and networking and built upmodel viagraphic theory， and given quantitative analysis ofTrigonometry debt in various way according to differentcircumstances．Actually From the view of the graphic theory，clearing theTrigonometry debt is transforming a closed figure into an openedfigure．And tends to make their debts clear．Namely，try to simplify thedebt network maintaining the debts of all enterprises constant．Generally speaking, it is necessary to integrate qualitativeanalysis and quantitative analysis to study trigonometry debt,for an effective solutions.This paper also discusses the connectivity of graphs with two equal orbits.LetG be a graph with two equal vertex orbits V1and V₂. Then G[V₁] isk-regular graph, G[V₂] is r-regular graph and G[V₁, V₂] is l-regular bipartite graph. In this paper, we show that κ（G）≥min{k, r}+1.Further, a series examples show that our result is best possible.
