Kappa-Slender Modules
Radoslav Dimitric
For an arbitrary infinite cardinal , we define classes of coordinatewise -slender and tailwise -slender modules as well as related classes of -modules and initiate a s…
Mathematics: abstraction and reality. A sketch toward deeper analysis
Radoslav Dimitric
This paper establishes grounds for deeper exploration into the question of dual nature of mathematics as an abstract discipline and as a concrete science. It is argued, as one of t…
Hom commuting with filtered products
Radoslav Dimitric
In a sufficiently rich category, such as a category of R-modules, and a given infinite cardinal , we examine classes $\Cal H^κ_*$ of objects M, such that the following natural m…
Feedback from students' tests as a tool in teaching
Radoslav M. Dimitrić
A close look at students' written work on examinations offers a wealth of information about their performance, their knowledge of the subject, their strengths, weaknesses and misco…
Is the function 1/x continuous at 0?
Radoslav M. Dimitric
Brief development of the idea of the very important notion of continuity is given. Continuity is often confused with contiguity, "drawing the graph in one go," "no gaps," etc. The…
A Note on Surjective Inverse Systems
Radoslav Dimitric
Given an upward directed set we consider surjective -inverse systems $\{X_\al,f_{\al\be}:X_\be\lra X_\al| \al\leq\be\in I\}$, namely those inverse systems that have all $f_{…
