A degenerate version of hypergeometric Bernoulli polynomials: announcement of results

Abstract This article explores some properties of degenerate hypergeometric Bernoulli polynomials, which are defined through the following generating function <m:math xmlns:m="http://www.w3.org/1998/Math/MathML" display="block"> <m:mrow> <m:mfrac> <m:mrow> <m:msup> <m:mrow> <m:mi>t</m:mi> </m:mrow> <m:mi>m</m:mi> </m:msup> <m:msubsup> <m:mrow> <m:mi>e</m:mi> </m:mrow> <m:mi>λ</m:mi> <m:mi>x</m:mi> </m:msubsup> <m:mrow> <m:mo>(</m:mo> <m:mi>t</m:mi> <m:mo>)</m:mo> </m:mrow> </m:mrow> <m:mrow> <m:msubsup> <m:mrow> <m:mi>e</m:mi> </m:mrow> <m:mi>λ</m:mi> <m:mi>x</m:mi> </m:msubsup> <m:mrow> <m:mo>(</m:mo> <m:mi>t</m:mi> <m:mo>)</m:mo> </m:mrow> <m:mo>-</m:mo> <m:msubsup> <m:mo>∑</m:mo> <m:mrow> <m:mi>l</m:mi> <m:mo>=</m:mo> <m:mn>0</m:mn> </m:mrow> <m:mrow> <m:mi>m</m:mi> <m:mo>-</m:mo> <m:mn>1</m:mn> </m:mrow> </m:msubsup> <m:mrow> <m:mrow> <m:mo>(</m:mo> <m:mn>1</m:mn> <m:mo>)</m:mo> </m:mrow> <m:mi>l</m:mi> <m:mo>,</m:mo> <m:mi>λ</m:mi> <m:mfrac> <m:mrow> <m:msup> <m:mrow> <m:mi>t</m:mi> </m:mrow> <m:mi>l</m:mi> </m:msup> </m:mrow> <m:mrow> <m:mi>l</m:mi> <m:mo>!</m:mo> </m:mrow> </m:mfrac> </m:mrow> </m:mrow> </m:mfrac> <m:mo>=</m:mo> <m:munderover> <m:mo>∑</m:mo> <m:mrow> <m:mi>n</m:mi> <m:mo>=</m:mo> <m:mn>0</m:mn> </m:mrow> <m:mrow> <m:msup> <m:mrow/> <m:mo>∞</m:mo> </m:msup> </m:mrow> </m:munderover> <m:mrow> <m:msubsup> <m:mrow> <m:mi>B</m:mi> </m:mrow> <m:mrow> <m:mi>n</m:mi> <m:mo>,</m:mo> <m:mi>λ</m:mi> </m:mrow> <m:mrow> <m:mrow> <m:mo>[</m:mo> <m:mrow> <m:mi>m</m:mi> <m:mo>-</m:mo> <m:mn>1</m:mn> </m:mrow> <m:mo>]</m:mo> </m:mrow> </m:mrow> </m:msubsup> </m:mrow> <m:mrow> <m:mo>(</m:mo> <m:mi>x</m:mi> <m:mo>)</m:mo> </m:mrow> <m:mfrac> <m:mrow> <m:msup> <m:mrow> <m:mi>t</m:mi> </m:mrow> <m:mi>n</m:mi> </m:msup> </m:mrow> <m:mrow> <m:mi>n</m:mi> <m:mo>!</m:mo> </m:mrow> </m:mfrac> <m:mo>,</m:mo> <m:mi> </m:mi> <m:mi> </m:mi> <m:mi> </m:mi> <m:mi> </m:mi> <m:mrow> <m:mo>|</m:mo> <m:mi>t</m:mi> <m:mo>|</m:mo> </m:mrow> <m:mo>&lt;</m:mo> <m:mo>min</m:mo> <m:mrow> <m:mo>{</m:mo> <m:mrow> <m:mn>2</m:mn> <m:mi>π</m:mi> <m:mo>,</m:mo> <m:mfrac> <m:mn>1</m:mn> <m:mrow> <m:mrow> <m:mo>|</m:mo> <m:mi>λ</m:mi> <m:mo>|</m:mo> </m:mrow> </m:mrow> </m:mfrac> </m:mrow> <m:mo>}</m:mo> </m:mrow> <m:mo>,</m:mo> <m:mi>λ</m:mi> <m:mo>∈</m:mo> <m:mi>ℝ</m:mi> <m:mo>\</m:mo> <m:mrow> <m:mo>{</m:mo> <m:mn>0</m:mn> <m:mo>}</m:mo> </m:mrow> <m:mo>.</m:mo> </m:mrow> </m:math> {{{t^m}e_\lambda ^x\left( t \right)} \over {e_\lambda ^x\left( t \right) - \sum\nolimits_{l = 0}^{m - 1} {\left( 1 \right)l,\lambda{{{t^l}} \over {l!}}} }} = \sum\limits_{n = 0}^{^\infty } {B_{n,\lambda }^{\left[ {m - 1} \right]}} \left( x \right){{{t^n}} \over {n!}},\,\,\,\,\left| t \right| &lt; \min \left\{ {2\pi ,{1 \over {\left| \lambda \right|}}} \right\},\lambda \in \mathbb{R}\backslash \left\{ 0 \right\}.
