Analytical approximation to solutions of singularly perturbed boundary value problems.
The Heisenberg uncertainty relation in harmonic analysis on -adic numbers field
In this paper, two important geometric concepts–grapical center and width, are introduced in -adic numbers field. Based on the concept of width, we give the Heisenberg uncertainty relation on harmonic analysis in -adic numbers field, that is the relationship between the width of a complex-valued function and the width of its Fourier transform on -adic numbers field.
Weyl-Heisenberg frame in -adic analysis
In this paper, we establish an one-to-one mapping between complex-valued functions defined on and complex-valued functions defined on -adic number field , and introduce the definition and method of Weyl-Heisenberg frame on hormonic analysis to -adic anylysis.
