Nature, 1870 WILL you permit me to say a few words on the interesting question raised by Dr. Ingleby in your last? The sun, moon and all the heavenly bodies appear set, as it were, in the blue sky when the weather is clear; and as they are rarely visible unless when surrounded by at least a small space of blue sky, it seems to me that they will be naturally judged ...

A GRAPH WHICH RECOGNIZES IDEMPOTENTS OF A COMMUTATIVE RING [PDF]
Journal of Algebraic Systems, 2020 In this paper we introduce and study a graph on the set of ideals of a commutative ring $R$. The vertices of this graph are non-trivial ideals of $R$ and two distinct ideals $I$ and $J$ are adjacent if and only $IJ=Icap J$.

On the diameter of an ideal [PDF]
Journal of Algebra, 2018 We begin the study of the notion of diameter of an ideal I of a polynomial ring S over a field, an invariant measuring the distance between the minimal primes of I. We provide large classes of Hirsch ideals, i.e. ideals with diameter not larger than the codimension, such as: quadratic radical ideals of codimension at most 4 and such that S/I is ...

Solar Physics, 1983 AbstractBecause of the renewed attention now paid to the solar diameter, its variations from equator to pole, or its secular or long-period changes, the question: what is a solar diameter? is not meaningless. Two kinds of definitions may be given: either astrophysical, each one relating to a specific physical parameter, or observational, relating to a ...
