The dynamics of magma mixing in a rising magma batch
Bulletin Of Volcanology, 1989The conditions under which two magmas can become mixed within a rising magma batch are investigated by scaling analyses and fluid-dynamical experiments. The results of scaling analyses show that the fluid behaviours in a squeezed conduit are determined mainly by the dimensionless number

We give a completion theorem for ordered magmas (i.e. ordered algebras with monotone operations) in a general form. Particular instances of this theorem are already known, and new results follow. The semantics of programming languages is the motivation of such investigations.

Magma-joined-magmas: a class of new algebraic structures
2015Summary: By left magma-\(e\)-magma, I mean a set containing the fixed element \(e\), and equipped by two binary operations ``\(\cdot\)'' and \(\odot\) with the property \(e\odot (x\cdot y)=e\odot(x\odot y)\), namely left \(e\)-join law. So, \((X, \cdot, e, \odot)\) is a left magma-\(e\)-magma if and only if \((X, \cdot), (X, \odot)\) are magmas ...

There are four standard Moufang identities; call them (M1), (M2), (M3), and (M4) (their definitions are given below). In the variety of loops they are equivalent; that is, each of these identities implies the other three. It was shown in [Phillips and Vojtěchovský, A scoop from groups: New equational foundations for loops, Comment. Math. Univ.
