设TX是非空集合X上全变换半群,E是X上非平凡的等价关系,则TE(x)是TX的子半群.在赋予半群TE(X)自然偏序关系的条件下,本文刻画了它的相容元.......
Uniform Convergence for Finite Volume Element Method for Non-selfadjoint and Indefinite Elliptic Pro
In this paper, we prove the existence, uniqueness and uniform convergence of the solution of finite volume element metho......
设TX是全序集X={1<2<…<n}上的全变换半群,则Sn^-={f∈TX:■x∈X,f(x)≤x}是TX的降序变换子半群,赋予降序变换半群Sn^-自然偏序关......
