Motivated by their importance and potential for applications in certain problems in number theory, combinatorics, classical and numerical analysis, and other fields of applied mathematics, a variety of polynomials and numbers with their variants and extensions have recently been introduced and investigated. In this paper, we aim to introduce partially degenerate Laguerre–Bernoulli polynomials of the first kind and investigate some properties such as explicit summation formulas, addition formulas, implicit formulas and symmetry identities. Relevant connections of the results presented here with those relatively simple numbers and polynomials are considered.
2. Partially degenerate Laguerre–Bernoulli polynomials of the first kind

3. General identities
In our previous articles (Pathan and Khan [Citation24] and Haroon and Khan [Citation4] and Khan et al. [Citation14–16]), it was shown that symmetric identities for Hermite-based generalized polynomials unify many properties and identities of Hermite–Bernoulli and Hermite–Euler polynomials. In this section, we give general symmetric identities for partially degenerate Laguerre–Bernoulli polynomials of the first kind by applying the generating functions (Equation10
(10)

4. Concluding remarks
In this paper, we have presented the generalized partially degenerate Laguerre–Bernoulli polynomials of the first kind and discussed, in particular, some interesting series representations. We have deduced some relevant properties by using the structure and the relations satisfied by the recently generalized Laguerre polynomials incorporates the definition of partially degenerate Laguerre–Bernoulli polynomials of the first kind and a preliminary study of these polynomials. We derived some theorems on implicit summation formulae for partially degenerate Laguerre–Bernoulli polynomials of the first kind and their special cases are given. Finally, we derived symmetry identities for type partially degenerate Laguerre–Bernoulli polynomials of the first kind.
