I am trying to show directly (i.e., not using the Fourier transform) that if S=S(Rn)S=S(Rn) is the class of Schwartz functions then f,g∈Sf,g∈S implies f∗g∈Sf∗g∈S.The definition I have is f∈Sf∈S iff for all NN, ∥f∥N:=supx∈Rd,|α|,|β|≤N|xβ∂α...
In this paper, the Plancherel theorem is used to decompose K-compact Schwartz class functions (those with K-types in a compact set) as finite sums of wave packets. A new feature of the infinite center case is that the individual wave packets occurring in the decomposition of a Schwartz ...

Employing two methods we consider a class of n-dimensional functional equations in the space of Schwartz distributions. As the first approach, employing regularizing functions we reduce the equations in distributions to classical ones of smooth functions and find the solutions. Secondly, using differenti...
We give an explicit criterion for a rational lattice in the time-frequency plane to admit a Gabor frame with window in the Schwartz class.The criterion is an inequality formulated in terms of the lattice covolume, thedimension of the underlying Euclidean space, and the index of an associated...
The library provides an Fdt class which you can use like this: $ PYTHONPATH=../pylibfdt python3 >>> import libfdt >>> fdt = libfdt.Fdt(open('test_tree1.dtb', mode='rb').read()) >>> node = fdt.path_offset('/subnode@1') >>> print(node) 124 >>> prop_offset = fdt.first...

The traditional kernel functions K(x,y) of two variables of the theory of integral operators having been expanded in scope to include their generalized function analogues, which are allowed to be more singular in a serious way, a large class of operators from D to its dual space D′ of ...
This model is fairly satisfactory, allowing for the correct classifi- cation of 90% of the cases. Only one culture of the low group and one in the high were mistakenly classified. Finally, considering the discriminant functions obtained for each of the cultural dimensions, a ranking of ...
