Complete Asymptotic Expansion for Exponential-Type Operators Related to π₯4/3
Ulrich R. Abel, Vitaliy Kushnirevych Β· Mathematica Pannonica Β· 2025
In the present paper, we study the asymptotic properties of an exponential-type operator which was recently constructed. It is connected with π(π₯) = π₯4/3. The main result is a pointwise complete asymptotic expansion valid for locally smooth functions. All coefficients are derived and explicitly given.
