چکیده

We define the ε∞-product of a Banach space G by a quotient bornological space E | F that we denote by Gε∞(E | F ), and we prove that G is an L∞-space if and only if the quotient bornological spaces Gε∞(E | F ) and (GεE) | (GεF ) are isomorphic. Also, we show that the functor .ε∞. : Ban× qBan −→ qBan is left exact. Finally, we define the ε∞-product of a b-space by a quotient bornological space and we prove that if G is an εb-space and E | F is a quotient bornological space, then (GεE) | (GεF ) is isomorphic to Gε∞(E | F ).

STABILIZER TOPOLOGY OF HOOPS

In this paper, we introduce the concepts of right, left and product stabilizers on hoops and study some properties and the relation between them.  And we try to find that how they can be equal and investigate that under what condition they can be filter, implicative filter, fantastic and positive implicative filter. Also, we prove that  right and product stabilizers are filters and if they are ...

Uniform connectedness and uniform local connectedness for lattice-valued uniform convergence spaces

We apply Preuss' concept of $mbbe$-connectedness to the categories of lattice-valued uniform convergence spaces and of lattice-valued uniform spaces. A space is uniformly $mbbe$-connected if the only uniformly continuous mappings from the space to a space in the class $mbbe$ are the constant mappings. We develop the basic theory for $mbbe$-connected sets, including the product theorem. Furtherm...

Mushtaq Shaker Abdul-Hussein and G.S. Srivastava A STUDY OF BORNOLOGICAL PROPERTIES OF THE SPACE OF ENTIRE FUNCTIONS REPRESENTED BY MULTIPLE DIRICHLET SERIES

The space of entire functions represented by Dirichlet series of several complex variables has been studied by S. Dauod [1]. M.D. Patwardhan [6] studied the bornological properties of the space of entire functions represented by power series. In this work we study the bornological aspect of the space Γ of entire functions represented by Dirichlet series of several complex variables. By Γ we den...
