Constructions of three kinds of Bihom-superalgebras

<p style='text-indent:20px;'>The purpose of this paper is to study the constructions between Bihom-alternative superalgebras and Bihom-Malcev superalgebras and Bihom-Jordan superalgebras. First, we explain in detail that every regular Bihom-alternative superalgebra could be Bihom-Malcev-admissible superalgebra or Bihom-Jordan-admissible superalgebra. Next, the bimodules and <inline-formula><tex-math id="M1">\begin{document}$ T^*_\theta $\end{document}</tex-math></inline-formula>-extensions of Bihom-alternative superalgebras are also discussed as properties of Bihom-alternative superalgebras.</p>
