The freeness problem over matrix semigroups and bounded languages [PDF]
peer reviewedWe study the freeness problem for matrix semigroups. We show that the freeness problem is decidable for upper-triangular 2 × 2 matrices with rational entries when the products are restricted to certain bounded ...

ON THE UNDECIDABILITY OF FREENESS OF MATRIX SEMIGROUPS
International Journal of Algebra and Computation, 1999We slightly improve the result of Klarner, Birget and Satterfield, showing that the freeness of finitely presented multiplicative semigroups of 3×3 matrices over ℕ is undecidable even for triangular matrices. This is achieved by proving a new variant of Post correspondence problem. We also consider the freeness problem for 2×2 matrices.

ON THE FREENESS OF 3-ARRANGEMENTS
Bulletin of the London Mathematical Society, 2005The author considers the freeness of hyperplane arrangements in a 3-dimensional space. A hyperplane arrangement \(A\) in an \(l\)-dimensional linear space is free, with exponents \(\exp(A) = (1=d_1, d_2, \ldots, d_l)\), if the associated module of all logarithmic vector fields is free with basis \(\delta_1, \ldots, \delta_l\), such that \(\deg \delta_i

Triangle-Freeness is Hard to Detect
Combinatorics, Probability and Computing, 2002We show that recognizing the K3-freeness and K4-freeness of graphs is hard, respectively, for two-player nondeterministic communication protocols using exponentially many partitions and for nondeterministic syntactic read-r times branching programs.The key ingredient is a generalization of a colouring lemma, due to Papadimitriou and Sipser, which ...

Continuity, freeness, and filtrations
Journal of Applied Non-Classical Logics, 2010The role played by continuous morphisms in propositional modal logic is investigated: it turns out that they are strictly related to filtrations and to suitable variants of the notion of a free alg...

A Hopf Algebra Freeness Theorem
American Journal of Mathematics, 1989The authors prove the conjecture that every finite-dimensional Hopf algebra H over a field k is a free (left or right) module over any Hopf subalgebra B. This was first proved by the second author in the case when \(B=kG\), G the group of group-like elements, is semi-simple [J.

On the pseudo-freeness and the CDH assumption
International Journal of Information Security, 2009The notion of pseudo-free group was first introduced by Hohenberger (Master’s thesis, EECS Dept., MIT, 2003). Rivest (TCC 2004. LNCS 2951, 505–521, 2004) formalized it and showed that several standard cryptographic assumptions hold on pseudo-free groups, such as the RSA assumption, the strong RSA assumption and the discrete logarithm assumption. Rivest
