on hyper bi-algebras

In this paper, we introduce the notion of hyper bi-algebra and investigate some properties of it. also, we state and prove some theorems which determine the rela-tionship among r/c/d/t and v-hyper bi-algebras un-der some conditions. then we study the relation among hyper bi-algebra with some of other hyper logical alge-bras such as hyper bci/bck/k/b/bcc-algebras and show that under which condition these hyper structures coincide. in addition, we define hyper subalgebra and (weak) ideal of a hyper bi-algebra and obtain some re-sults and the relation between them. finally, we con-struct the quotient structure of hyper bi-algebra and ex-amine the isomorphism theorems.
