Fractal Convolution Bessel Sequences on Rectangle
Frontiers in Industrial and Applied Mathematics(2023)
Abstract
Fractal functions provide a natural deterministic approximation of complex phenomena and also it has self-similarity. Recently, it has been recognized as an internal binary operation, called fractal convolution. In the present article, we obtain Bessel sequences of
$$L^2(\mathcal {I} \times \mathcal {J})$$
composed of product of fractal convolutions, using the identification of
$$L^2(\mathcal {I} \times \mathcal {J})$$
with the tensor product space
$$L^2(\mathcal {I})\otimes L^2(\mathcal {J})$$
, where
$$\mathcal {I}$$
and
$$\mathcal {J}$$
are real compact intervals.
