Homomorphisms of Approximation Spaces
The notion of the homomorphism of approximation spaces is introduced. Some properties of homomorphism are investigated, and some characterizations of homomorphism are given.

Homomorphisms of planar signed graphs to signed projective cubes [PDF]
We conjecture that every signed graph of unbalanced girth 2g, whose underlying graph is bipartite and planar, admits a homomorphism to the signed projective cube of dimension 2g1.

A generalization of anti-homomorphisms [PDF]
We prove some nice properties of anti-homomorphisms, some of which are analogic to that of homomorphisms. Meanwhile, we develop a new kind of composition called $*$-composition such that the $*$-composition of two anti-homomorphisms is still an anti-homomorphism.

In this paper we study the notion of Smarandache loops. We obtain some interesting results about them. The notion of Smarandache semigroups homomorphism is studied as well in this paper.

On Enhancing Security for Division Homomorphism with ElGamal
Secure auctions and machine learning in cloud increasingly employs multi-party and homomorphic encryption support. A modification to Elgamal public key cryptosystem was shown to enable homomorphic division using an encoding of plaintext as fractions with

Infinitesimal Morita homomorphisms and the tree-level of the LMO invariant [PDF]
Let S be a compact connected oriented surface with one boundary component, and let P be the fundamental group of S. The Johnson filtration is a decreasing sequence of subgroups of the Torelli group of S, whose k-th term consists of the self ...

Torelli groups are subgroups of mapping class groups that consist of those diffeomorphism classes that act trivially on the homology of the associated closed surface. The Johnson homomorphism, defined by Dennis Johnson, and its generalization, defined by S. Morita, are tools for understanding Torelli groups.

Topology optimization for two-dimensional structures using boundary cycles in homology theory
Various prominent methods for structural topology optimization have been developed, especially since the late 1980s when the homogenization method was proposed.

Fuzzy Riesz homomorphism on fuzzy Riesz space [PDF]
In this paper, we give some properties of fuzzy Riesz homomorphism on fuzzy Riesz space. We give definitions of fuzzy quotient spaces, and some characterizations of fuzzy Archimedean quotient spaces. We prove the properties which fuzzy Riesz homomorphism is fuzzy order continuous, and study the extension of fuzzy lattice homomorphism and the extension ...
