Abstract

By left magma-e-magma, I mean a set containing
the fixed element e, and equipped by two binary operations "cdot"
, odot with the property eodot(xcdoty)=eodot(xodoty), 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 (groupoids), einX and the left e-join law holds.
Right (and two-sided) magma-e-magmas are defined in an analogous way.
Also, X is magma-joined-magma if it is magma-x-magma, for all xinX. Therefore, we introduce a big class of basic
algebraic structures with two binary operations which some of their
sub-classes are group-e-semigroups, loop-e-semigroups, semigroup-e-quasigroups,
etc. A nice infinite [resp. finite] example for them is real group-grouplike (mathbbR,+,0,+1) [resp. Klein group-grouplike].
In this paper, I introduce and study the topic, construct several big classes of such algebraic structures and characterize
all identical magma-e-magma in several ways. The motivation of this study lies in some
interesting connections to f-Multiplications, some basic functional equations
on algebraic structures and Grouplikes (recently been introduced by the author). At last, we show some of future directions
for the researches.
