Abstract
This article deals with the introduction of truncated exponential-based Appell polynomials and derivation of their properties. The operational correspondence between these polynomials and Appell polynomials is established. Also, an integral representation for these polynomials in terms of a recently introduced family of polynomials is derived. Special emphasis is given to the truncated exponential-based Bernoulli and Euler polynomials and their related numbers.

We give the surface plots of the polynomials \({}_{{}_{{{}_{[2]}}^e}}B_{n}(x,y)\), \({}_{{}_{{{}_{[2]}}^e}}E_{n}(x,y)\), \({}_{e}B_{n}(x,y)\), and \({}_{e}E_{n}(x,y)\), for \(n=5\). Also, we find the graphs of the polynomials \({}_{{}_{{{}_{[2]}}^e}}B_{n}(x)\), \({}_{{}_{{{}_{[2]}}^e}}E_{n}(x)\), \({}_{e}B_{n}(x)\), and \({}_{e}E_{n}(x)\), for \(n=5\). In order to draw the surface plots and graphs of these polynomials, we use the values of the Bernoulli polynomials \(B_n(x)\) and Euler polynomials \(E_n(x)\), for \(n=0,1,2,3,4,5.\) we give the list of first few Bernoulli and Euler polynomials in Table 3.
Now, using Table 3, we express the polynomials \({}_{{}_{{{}_{[2]}}^e}}B_{5}(x,y)\), \({}_{{}_{{{}_{[2]}}^e}}E_{5}(x,y)\), \({}_{e}B_{5}(x,y)\), and \({}_{e}E_{5}(x,y)\) in powers of x and y and the polynomials \({}_{{}_{{{}_{[2]}}^e}}B_{5}(x)\), \({}_{{}_{{{}_{[2]}}^e}}E_{5}(x)\), \({}_{e}B_{5}(x)\), and \({}_{e}E_{5}(x)\) in powers of x. We present the expressions of these polynomials in Table 4.
By making use of expressions given in Table 4, we get the following surface plots and graphs:
