unconditional convergence

基本解释

In the case X is R or C, the unconditional convergence and absolute convergence as well as summability of an infinite series are equivalent.
当X为数域时，无条件收敛性与绝对收敛性及可和性是等价的。
By using the energy method, the second-order convergence and unconditional stability of the schemes are proved. By the extrapolation technique, the linearized schemes are devised.
用能量估计的方法证明了此格式的二阶收敛性和无条件稳定性；
Locally implicit finite element method is a satisfactory numerical method to solve non-linear partial differential equations for its unconditional stability and its high rate of convergence.
认为局部隐式有限元法是一种绝对稳定的方法，且具有快速收敛的性质，是求解非线性偏微分方程的一种有效的数值算法。
