Abstract
In this paper we present a new type of extended uncertainty principle (EUP) of the form [X, P] = i(1 − q|X|) and show that it has the non-zero minimal momentum. For this EUP we discuss the classical mechanics in the curved space, deformed calculus, deformed quantum mechanics and Bohr-Sommerfeld quantization.

When x > 0, the deformed exponential function can also be written as
When x < 0, the deformed exponential function can also be written as
If we introduce the q-number as
we have
where
and
The q-Gamma function is defined by
Limiting q → 0, the (129) reduces to an ordinary Gamma function. For z = N, (N = 0, 1, 2, ⋯), we have
The q-Gamma function satisfies the following recurrence relation:
This is the q-analogue of basic functional relation for the ordinary Gamma function. The q-Gamma function for arbitrary number z can also be written as follows:
Indeed, replacing z with z + 1, we have
A glance at the (132) shows
and
From the definition (132), we have the third definition of q-Gamma function as follows:
Using the (136), we find the following relations for the product of two q-Gamma functions:
Inserting z = 1/2 into the (137), we have
The q-deformed digamma function is defined as
Using the property of the q-log function, we have the following result:
Inserting z = 0 into the (140) yields
where the q-analogue of Euler constant is then given by
Appendix B: Nikiforov - Uvarov Method
In this technique, we solve a second-order differential equation in the form of a hypergeometric-type or a general Schrodinger-type equation [1, 2],
For calculation of eigenvalues and corresponding wave functions of the energy by using this approach, we try to obtain the following parameters
The energy relation using the set of parameters mentioned above forms an energy equation as,
Also, the final wave function relation in NU method will be of the following form,
If α3 = 0 , the relation (147) will be reduced to
