The Characterization of the Regularity of the Jacobian Determinant in the framework of Potential spaces

چکیده
We give necessary and suucient conditions on the parameters s 1 ; s 2 such that the Jacobian determinant extends to a bounded operator from _ H s1 p1 _ H s2 p2 : : : _ H sm pm into Z 0. Here all spaces are deened on R n and 2 m n. In almost all cases the regularity of the Jacobian determinant is calculated exactly.

CONNECTING T AND LATTICE-VALUED CONVERGENCES
$top$-filters can be used to define $top$-convergence spaces in the lattice-valued context. Connections between $top$-convergence spaces and lattice-valued convergence spaces are given. Regularity of a $top$-convergence space has recently been defined and studied by Fang and Yue. An equivalent characterization is given in the present work in terms of convergence of closures of $top$-filters. M...
متن کاملThe Role of Garden and Courtyard in Organizing the Space of Aristocratic Houses in Tehran during Qajar’s Era
Constructing houses in the form of garden-house became popular among Statesmen and the privileged class in Naseri period. Iranian traditional houses which used to be formed around a central courtyard, now were organized around a garden. So the transition from houses with courtyard to garden-houses created a new order of relationships between spaces, resulted in redefining spaces and their forms...
متن کاملArens regularity of bilinear forms and unital Banach module spaces
Assume that $A$, $B$ are Banach algebras and that $m:Atimes Brightarrow B$, $m^prime:Atimes Arightarrow B$ are bounded bilinear mappings. We study the relationships between Arens regularity of $m$, $m^prime$ and the Banach algebras $A$, $B$. For a Banach $A$-bimodule $B$, we show that $B$ factors with respect to $A$ if and only if $B^{**}$ is unital as an $A^{**}$-module. Le...
متن کاملArens Regularity and Weak Amenability of Certain Matrix Algebras
Motivated by an Arens regularity problem, we introduce the concepts of matrix Banach space and matrix Banach algebra. The notion of matrix normed space in the sense of Ruan is a special case of our matrix normed system. A matrix Banach algebra is a matrix Banach space with a completely contractive multiplication. We study the structure of matrix Banach spaces and matrix Banach algebras. Then we...
متن کاملFuzzy convergence structures in the framework of L-convex spaces
In this paper, fuzzy convergence theory in the framework of $L$-convex spaces is introduced. Firstly, the concept of $L$-convex remote-neighborhood spaces is introduced and it is shown that the resulting category is isomorphic to that of $L$-convex spaces. Secondly, by means of $L$-convex ideals, the notion of $L$-convergence spaces is introduced and it is proved that the category of $L$-con...
