Webb在數學中,某個集合 X 的子集 E 的下確界(英語: infimum 或 infima ,記為 inf E)是小於或等於的 E 所有其他元素的最大元素,其不一定在 E 內。 所以還常用術語最大下界(簡寫為 glb 或 GLB)。在數學分析中,實數的下確界是非常重要的常見特殊情況。 但這個定義,在更加抽象的序理論的任意偏序集合中 ... WebbSorted by: 52. The main difference is that the infimum and supremum always exists (if you allow the values ± ∞) but the minimum and maximum doesn't. If the set is finite then it is trivial, as a finite set always has a maximal and minimal element, but if you look at something like: A = {x ∈ Q: x > 0}. Then you cannot find a smallest ...

Webbverification of the inf-sup condition for the bilinear form b(;)or simply called div-stability for Stokes equations. Note that the inf-sup condition (B) in the continuous level implies: for any q h 2P h, there exists v2V such that b(v;q h) kvk Vkq hk P and kvk Ckq hk. For the discrete inf-sup condition, we need a v h2V hsatisfying such property.
