FUZZY WEAK $n$-INNER PRODUCT SPACE

The paper is concerned with fuzzy real numbers and Felbin-type fuzzy inner product spaces. At first, we study fuzzy 2-inner product and discuss a few basic results of fuzzy inner product and fuzzy $2$-inner product. The existence of fuzzy $2$-inner product is proved with the help of an example. We introduce the notion of Felbin- type fuzzy weak $n$-inner product, which is a generalized concept of fuzzy $n$-inner product. Finally, we construct an $n$-iterated fuzzy $2$-inner product and prove that it is a fuzzy weak $n$-inner product, also furnish an example of a $3$-iterated fuzzy $2$-inner product which is not a fuzzy $3$-inner product.
