A
q-space (q-time)-deformation of the continuity equations are introduced using
the q- derivative (or Jackson derivative). By quantum calculus, we solve such
equations. The free cases are discussed separately. |

Continuity equations can comprise both "source" and
"sink" items, which permit them to give an account of amounts that
are almost preserved, such as the density of sorts of molecules which can be
produced or demolished by chemical interactions. That is to say Continuity equations underlie more specific transfer
equations like Navier–Stokes equations, Boltzmann transport equation, and the
convection spread equation. By the diversity theory, a comprehensive continuity equation can also
be shaped in a” variant form”: σ is the
generation of Q per unit volume per unit time, it is time; j is the
flux of Q, ρ is the amount of the quantity Q per unit volume where
∇ is divergence When Q is a preserved quantity that cannot be formed or ruined (such
as energy), σ = 0 and the equations become: In the field of Mathematics,
a q-analog of a theory, sameness or manifestation is an act of generalizing,
counting another parameter q that returns the original theory, expression in
the limit as q → 1. Mathematicians are, typically, interested in
q-analogs that rise naturally, rather than in randomly devising q-analogs of
known results. The earliest q-analog dealt with in detail is the basic hyper
geometric series, which was presented in the 19th century. |

In this way, it is normal to ask what is the q-Space (q-time)-deformation of the continuity equation.
The present paper has been arranged as follows:
Section 1 introduces the topic theory. Section 2 briefly will give an exposition of some basic concept and preliminaries of the language of q-calculus. In section 3, we introduced free q-Space (free q-time)-continuity equation, and we deduced some theorems. Finally, in Section 4, we study q-Space (q-time)-deformation of the continuity equation.
In future works, we will try to extend the continuity equation in the quantum white noise setting, see [8 and 9]
2. PRELIMINARIES
We will give an exposition of some basic concept and preliminaries of the language of q-calculus (see [1, 2, 3, 4, 5, 6, and 7]). Therefore, natural number n has the following q deformation:

Sporadically we will write [∞] q for the limit of these numbers: 1/((1-q)). The q factorials and q binomial coeffcients are defined naturally as
with
For q ∈ (0,1) and analytic f:C⟶C define operators Z and D_ (q) as follows:
