In the present paper the author introduces the concept of almost slender modules, which is very useful for studying the Cartesian products of modules over a Dedekind domain. The ring R is called slender [see \textit{E. L. Lady}, Pac. J. Math. 49, 397-406 (1973; Zbl 0274.16015)] if for every homomorphism \(f: \prod^{\infty}_{i=1}A_ i\to R\), where ...

When we say in analytic geometry that a point has co-ordinates (x, y), the order in which x and y occur, in the symbol (x, y), is important: (1, 2) ≠ (2, 1). For this reason we call (x, y) an ordered pair. Moreover, x and y come from sets; in this case x, y ∈ R. This idea can be generalizedf as follows. Let 𝒰 be a universe.

On the Discrepancy for Cartesian Products
Journal of the London Mathematical Society, 2000We prove that the discrepancy for the family of Cartesian products \(B_1\times B_2\subseteq \mathbb{R}^4\), where \(B_1\) and \(B_2\) are circular discs in the plane, is \(O(n^{1/4+\varepsilon})\) for an arbitrarily small constant \(\varepsilon>0\), i.e. essentially the same as that for discs in the plane.

0. Introduction. Let as be an arc in the interior In of the n-cell In and let X be the quotient space I"/ac obtained by shrinking a to a point. According to Kwun and Raymond [4], X X 12 is an (n + 2)-cell. The crucial tool in their proof is the result of Andrews-Curtis that, under the above conditions, In/a X R1 is homeomorphic to In XR1.
