The aim of this paper is to establish common fixed point results for multivalued mappings satisfying generalized F-contractive conditions of Hardy Rogers type with respect to generalized dynamic process in *b*-metric space. Our results improve and generalize several well known results in the existing literature.

Let be a non empty set, be a mapping. A point is called a fixed point of if Fixed points results of mappings, which satisfies some specific contractive conditions on some space have been very useful in research activity (see ^{ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30}).

Recently, Wardowski ^{ 30} introduced a new concept of contraction named F-contraction and proved a fixed point theorem which generalizes Banach contraction principle. Klim et al. ^{ 22} further established fixed point result for F-contractive mapping in dynamic process. Cosentino et al. ^{ 16} further generalized this concept as F-Contractive Mappings of Hardy-Rogers-Type. Arshad et al. ^{ 4} proved fixed point result in contraction of Hardy-Rogers-type. Following this direction of research, in this paper, we will present some fixed point results of Hardy-Rogers-type for multivalued mappings in b-metric space with generalized dynamic process. This paper contain common fixed point results for two mappings. Throughout our paper and represent set of real numbers, set of natural numbers and family of non-empty closed bounded subsets respectively.

**Definition** **12** *Let** ** **be a b-metric space,** ** **is continuous** ** **and** ** **be **an arbitrary point in** **.

*for all** ** **with** ** where** ** ** ** ** **and*

Now we state and prove our main result.

**Theorem** **13*** Let** ** **be a complete b-metric space and** ** **If** ** **is a generalized multivalued** -contraction of Hardy-Rogers-type with respect to a generalized dynamic process** ** Then** ** **and** ** **have a common fixed point*.

**Proof****:** Let be an arbitrary point, by definition of generalized multivalued -contraction of Hardy-Rogers-type with respect to a generalized dynamic process we have

As is strictly increasing, therefore

As and we deduce that and so

This implies that

Continuing this process, we can easily say that

Now, to show that is a Cauchy sequence in . Let with

Using Lemma 10, and taking limit we get

which proves that is a Cauchy, so there exist some such that Now we prove that For this, we have

By (F2)

Therefore

From above we can write

Again by (F2) Therefore So . Moreover

Hence, , so , that is is the common fixed point of and .

Putting , we obtain a generalize form of Kannan's result in dynamic process.

**Corollary**** 14**** ***Let** ** **be a complete b-metric **space and** ** Assume that there exist** ** **and** ** **such that ** **is continuous satisfying*:

*for all** ** **with** ** , where** ** ** **,** ** **and** ** . Then** ** **and** ** **have a common fixed point**.*

Choosing , we obtain a generalize version of Reich's result.

**Corollary**** 15**** ***Let** ** **be a complete b-metric space and** ** Assume that there exist** ** **and** ** **such that** ** **is continuous satisfying*:

for all with , where , and . Then and have a common fixed point.

**Theorem**** 16**** **Let * **be a complete b-metric space,** ** **is continuous and** ** **Assume that there exist** ** **and** ** **such that ** **is continuous from the right. Now if** ** **is a generalized dynamic process such that*

(2) |

*where *

*for all** ** **with** ** where** ** ** ** ** **and** **. Then** ** **and** ** **have a common fixed point*.

**Proof:** Let be an arbitrary point of By definition of generalized dynamic process . Since is continuous from the right, there exists a real number such that

Now, from we deduce that there exists such that Consequently, we get

which implies

As is strictly increasing we deduce

As and hence we deduce that and so consequently,

Continuing this way we get

and hence

Proceeding this as in Theorem 13, we obtain that is a Cauchy sequence. Since is a complete metric space, there exists some such that . Now we prove that . For this, since

By (F2)

Therefore, Hence

By using (F2) which implies Also

Therefore hence that is

Replacing b-metric space by metric space in the above result we get the following corollary:

**Corollary**** 17**** ***Assume that** ** **is a complete metric space,** ** **is continuous and** ** **Assume that there exist** ** **and ** such that ** is continuous from the right**. Now if** ** **is a generalized dynamic process in such a way that*

*where *

*for each** ** **with** ** where** ** ** **and** ** Then** ** **and** ** **possess a common fixed point*.

**Example**** 18**** ***Assume that** ** **and** ** **is defined by*

*where** * *Define** ** ** **and** ** **by** ** ** **and** ** **Define a sequence** ** **by for all** ** ** **with** ** **and** ** **Then*

and so on. Here

Fix and clearly . We can check that is a b-metric. Now checking for all we can find some that satisfy the inequality (2) in such a way that for each Moreover is found to be the common fixed point of and

Putting and in the above result we get the following corollary:

**Corollary**** 19** *Assume that** ** **is a complete b-metric space,** ** **is continuous*,* ** there exist a function** ** **and let** ** **satisfy (F1)-(F**2**). Now if** ** **is a generalized dynamic process in such a way that*

*then there is a common fixed point of** ** **and** ** **i.e.*

Putting as an identity function in Corollary 19 we get:

**Corollary**** 20*** Assume that** ** **is a complete metric space*,* ** **is continuo**u**s** ** there exist a function** ** **and suppose** ** **satisfy **(F1)-(F2**). Now if** ** **is a dynamic process in such a way that*:

then there exists a fixed point of
