1) uniton number
uniton数
1.
By using the simplified method of factorization given by Valli, and the correspondence between the harmonic map φ∶S 2→U(N) and U(N) uniton bundle ν(φ) with energy corresponding to the bundles second Chern class, which is established by Anand, the energy in a case φ∶S 2→U(N) is investigated in order to estimate the energy of a uniton using the uniton number.
采用Valli提出的简化的因子分解方法以及Anand建立的调和映射 φ∶S2 →U(N )与U (N) uniton丛ν(φ) 之间的对应 ,其中丛ν(φ)具有和丛的第二陈类相对应的能量 ,对如何利用uniton数来估计uniton的能量进行了研究 ,证明了Uhlenbeck的因式分解也是一种借助能量减少的因式分解 ,并给出了一种利用uniton数来估计uni ton的能量的方法 。
