We establish a method of Gröbner–Shirshov bases for trialgebras and show that there is a unique reduced Gröbner–Shirshov basis for every ideal of a free trialgebra. As applications, we give a method for the construction of normal forms of eleme

Image deblurring under the background of impulse noise is a typically ill-posed inverse problem which attracted great attention in the fields of image processing and computer vision. The fast total variation deconvolution (FTVd) algorithm proved to b

The total variation (TV) regularization-based methods are proven to be effective in removing random noise. However, these solutions usually have staircase effects. This paper proposes a new image reconstruction method based on TV regularization with

Models based on total variation (TV) regularization are proven to be effective in removing random noise. However, the serious staircase effect also exists in the denoised images. In this study, two-dimensional total variation with overlapping group s

We first construct linear bases for free Lie-admissible algebras and develop a new theory of Grobner–Shirshov bases for Lie-admissible algebras. Then we prove an analogue of the Poincare–Birkhoff–Witt theorem, that is, every Lie algebra L can b

We give a construction of the free digroup on a set X and describe the halo and the group parts of it. We prove that the free digroup on X is isomorphic to the free digroup on a set Y if and only if $$card(X)=card(Y)$$ .
