A Remark on Supra-additive and Supra-multiplicative Operators on C(x)
M.Radulescu proved the following result: Let X be a compact Hausdorff topological space and π : C(X)→ C(X) a supra-additive and supra-multiplicative operator. Then π is linear and multiplicative. We generalize this result to arbitrary topological spaces.
متن کاملParacompactness on supra topological spaces
In this article, we present the concept of supra paracompact spaces and study its basic properties. We elucidate its relationship with supra compact spaces and prove that the property of being a supra paracompact space is weakly hereditary and topological properties. Also, we provide some examples to show some results concerning paracompactness on topology are invalid on supra topology. Finally...
متن کاملrange supra - additive slowdown of water rotation †
The anion-cation interactions are optimized against the experimentally determined solution activity derivative at 2.5 m. This property directly depends on ion-ion interactions, thus making it an excellent target for parameterization. We opt for this indirect approach because directly parameterizing anion-cation interactions from quantum mechanical calculations is not feasible, as described belo...
متن کاملAddison on the `supra-renal Capsules'*
ADULATION of Addison and Bright in Britain's medical circles resounds only slightly less loudly than Harveian songs of praise. These men carry a large share of legendary British medicine in their names. Of recent years Harvey's worthiness of such a role has been the subject of several studies; as a result he has, if possible, gained in stature. What of Addison? The question is prompted by the a...
متن کاملSupra-Convergent Schemes on Irregular Grids
As Tikhonov and Samarskiï showed for k = 2, it is not essential that Ath-order compact difference schemes be centered at the arithmetic mean of the stencil's points to yield second-order convergence (although it does suffice). For stable schemes and even k, the main point is seen when the k th difference quotient is set equal to the value of the k th derivative at the middle point of the stenci...
