Ring-ring tautomerism

Chemistry of Heterocyclic Compounds, 1992
The superposition within a single molecule of competing ring-chain tautomeric pairs, the minimum structural requirement of which is the presence of one nucleophilic (OH, NH, SH, etc.) and two electrophilic (C=N, C=O, etc.) centers or the reverse, is a method of constructing ring-ring or ring-chain-ring tautomeric systems. On the basis of the structural

COUNTABLE RINGS AS ENDOMORPHISM RINGS

The Quarterly Journal of Mathematics, 1988
Let \(\sum \leq \prod\) be the direct sum and product of countably many copies of the integers, let \(\sum \leq D\leq \prod\) such that D/\(\sum\) is the divisible part of \(\prod /\sum\), and let \(e_ n=(\delta_{in})_{i\in {\mathbb{N}}}\in \prod\) be the generalized n-th unit vector.
