In this paper, investigating the nonassociative version of groupoids and inverse semigroups, we study the relationship between these two algebraic structures and show that it can not be one-to-one.

A half-isomorphism φ : G → K between multiplicative systems G and K is a bijection from G onto K such that φ ( a b ) ∈ { φ ( a ) φ ( b ) , φ ( b ) φ ( a ) } for any a , b ∈ G . For groups all half-isomorphisms are either isomorphisms or a

Automorphic loops, or A-loops, are loops in which all inner mappings are automorphisms. Here, we investigate a class of A-loops known as the dihedral automorphic loop, denoted by Dih(α,G). This cla...

Automorphic loops, or A-loops, are loops in which all inner mappings are automorphisms. We investigated A-loops arising from a Lie algebra and describe their automorphism group. Also, we identify and describe their inner mapping group.

We give some necessary and sufficient conditions for the equivalency of the following two properties for a Moufang loop Q: Q over the nucleus Q/N is an abelian group and Q over the center is a group. We study those properties of Moufang loops which g

We classify all unital subalgebras of the Cayley algebra 𝕆(q) over the finite field Fq, q = pn. We obtain the number of subalgebras of each type and prove that all isomorphic subalgebras are conjugate with respect to the automorphism group of 𝕆
