Symmetric modules over their endomorphism rings

Ungor, B.; Kurtulmaz, Y.; Halicioglu, S.; Harmanci, A. (Algebra and Discrete Mathematics, 2015)

Let R be an arbitrary ring with identity and M a right R-module with S=EndR(M). In this paper, we study right R-modules M having the property for f,g∈EndR(M) and for m∈M, the condition fgm=0 implies gfm=0. We prove that ...
Towards practical private information retrieval from homomorphic encryption

Zhuravlev, D. (Algebra and Discrete Mathematics, 2015)

Private information retrieval (PIR) allows a client to retrieve data from a remote database while hiding the client's access pattern. To be applicable for practical usage, PIR protocol should have low communication and ...
Ultrafilters on G-spaces

Petrenko, O.V.; Protasov, I.V. (Algebra and Discrete Mathematics, 2015)

For a discrete group G and a discrete G-space X, we identify the Stone-Cech compactifications βG and βX with the sets of all ultrafilters on G and X, and apply the natural action of βG on βX to characterize large, thick, ...
