By using \$r\$-fuzzy regular semi open (closed) sets, we define a new fuzzy closure operator namely \$r\$-fuzzy regular semi interior (closure) operator. Also, we introduce fuzzy regular semi continuous and fuzzy regular semi irresolute mappings. Moreover, we investigate the relationship among fuzzy regular semi continuous and fuzzy regular semi irresolute mappings. Finally, we have given some counter examples to show that these types of mappings are not equivalent. \$r\$-fuzzy regular semi open (closed) sets \$r\$-fuzzy regular semi interior (closure) operator Fuzzy regular semi continuous (irresolute) maps 2017 04 01 1 17 http://scma.maragheh.ac.ir/article_22080_6b6d5d86c4a101f32db67cdc439daa70.pdf

In this paper, the notion of  dynamic equivalence relation is introduced and then it is proved that this relation is an equivalence relation. Also, a new metric on the collection of all equivalence classes is introduced and it is proved that this metric is complete.

The iteration procedure is based on local fractional derivative operators. This approach provides us with a convenient way to find a solution with less computation as compared with local fractional variational iteration method. Some illustrative examples are discussed. The results show that the methodology is very efficient and a simple tool for solving integral equations.

Our results generalize Kannan and Chatterjea fixed point theorems on complete \$b\$-metric spaces. In particular, we show that two self-mappings satisfying a contraction type inequality have a unique common fixed point. We also give some examples to illustrate the given results. \$b\$-metric space Common fixed point Altering distance function 2017 04 01 77 86 http://scma.maragheh.ac.ir/article_23831_6c258f4180145f5370b887cf815cd897.pdf
