https://en.wikipedia.org/wiki/The%20Journal%20of%20Chemical%20Physics | The Journal of Chemical Physics is a scientific journal published by the American Institute of Physics that carries research papers on chemical physics. Two volumes, each of 24 issues, are published annually. It was established in 1933 when Journal of Physical Chemistry editors refused to publish theoretical works.

https://en.wikipedia.org/wiki/Alison%20Wong | Alison Wong (born 1960) is a New Zealand poet and novelist of Chinese heritage. Her background in mathematics comes across in her poetry, not as a subject, but in the careful formulation of words to white space and precision. She has a half-Chinese son with New Zealand poet Linzy Forbes. She now lives in Geelong.

https://en.wikipedia.org/wiki/Ascendant%20subgroup | In mathematics, in the field of group theory, a subgroup of a group is said to be ascendant if there is an ascending series starting from the subgroup and ending at the group, such that every term in the series is a normal subgroup of its successor.
The series may be infinite. If the series is finite, then the subgrou... |
https://en.wikipedia.org/wiki/Temporal%20Process%20Language | In theoretical computer science, Temporal Process Language (TPL) is a process calculus which extends Robin Milner's CCS with the notion of multi-party synchronization, which allows multiple process to synchronize on a global 'clock'. This clock measures time, though not concretely, but rather as an abstract signal whic... |
https://en.wikipedia.org/wiki/Characteristically%20simple%20group | In mathematics, in the field of group theory, a group is said to be characteristically simple if it has no proper nontrivial characteristic subgroups. Characteristically simple groups are sometimes also termed elementary groups. Characteristically simple is a weaker condition than being a simple group, as simple groups... |
https://en.wikipedia.org/wiki/Strictly%20simple%20group | In mathematics, in the field of group theory, a group is said to be strictly simple if it has no proper nontrivial ascendant subgroups. That is, is a strictly simple group if the only ascendant subgroups of are (the trivial subgroup), and itself (the whole group).
In the finite case, a group is strictly simple if ... |
https://en.wikipedia.org/wiki/Absolutely%20simple%20group | In mathematics, in the field of group theory, a group is said to be absolutely simple if it has no proper nontrivial serial subgroups. That is, is an absolutely simple group if the only serial subgroups of are (the trivial subgroup), and itself (the whole group).
In the finite case, a group is absolutely simple if... |
https://en.wikipedia.org/wiki/Supersolvable%20group | In mathematics, a group is supersolvable (or supersoluble) if it has an invariant normal series where all the factors are cyclic groups. Supersolvability is stronger than the notion of solvability.
Definition
Let G be a group. G is supersolvable if there exists a normal series
such that each quotient group is cycl... |
https://en.wikipedia.org/wiki/FC-group | In mathematics, in the field of group theory, an FC-group is a group in which every conjugacy class of elements has finite cardinality.
The following are some facts about FC-groups:
Every finite group is an FC-group.
Every abelian group is an FC-group.
The following property is stronger than the property of being ... |
https://en.wikipedia.org/wiki/Fully%20normalized%20subgroup | In mathematics, in the field of group theory, a subgroup of a group is said to be fully normalized if every automorphism of the subgroup lifts to an inner automorphism of the whole group. Another way of putting this is that the natural embedding from the Weyl group of the subgroup to its automorphism group is surjectiv... |
