Tightening the Complexity of Equivalence Problems for Commutative Grammars [PDF]

open access: yes, 2015
We show that the language equivalence problem for regular and context-free commutative grammars is coNEXP-complete. In addition, our lower bound immediately yields further coNEXP-completeness results for equivalence problems for communication-free Petri ...

Trace Equivalence Decision: Negative Tests and Non-determinism [PDF]

open access: yes, 2011
We consider security properties of cryptographic protocols that can be modeled using the notion of trace equivalence. The notion of equivalence is crucial when specifying privacy-type properties, like anonymity, vote-privacy, and unlinkability.

Permutation matrices and matrix equivalence over a finite field

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1981
Let F=GF(q) denote the finite field of order q and Fm×n the ring of m×n matrices over F. Let 𝒫n be the set of all permutation matrices of order n over F so that 𝒫n is ismorphic to Sn.

English denominal conversion verbs and their Estonian equivalents: comparing translations and J. Silvet’s English-Estonian dictionary

open access: yesEesti ja Soome-ugri Keeleteaduse Ajakiri, 2014
Conversion is a highly efficient and economical word-formation process. It has enriched the English vocabulary considerably; however, translators and lexicographers are faced with the challenge of finding suitable translation equivalents.

The Almost Equivalence by Asymptotic Probabilities for Regular Languages and Its Computational Complexities

open access: yes, 2016
We introduce p-equivalence by asymptotic probabilities, which is a weak almost-equivalence based on zero-one laws in finite model theory. In this paper, we consider the computational complexities of p-equivalence problems for regular languages and ...

Equivalences, Identities, Symmetric Differences, and Congruences in Orthomodular Lattices

open access: yes, 2003
It is shown that operations of equivalence cannot serve for building algebras which would induce orthomodular lattices as the operations of implication can. Several properties of equivalence operations have been investigated.

New Equivalence Tests for Hardy–Weinberg Equilibrium and Multiple Alleles

open access: yesStats, 2020
We consider testing equivalence to Hardy−Weinberg Equilibrium in case of multiple alleles. Two different test statistics are proposed for this test problem. The asymptotic distribution of the test statistics is derived.

Non-commutative crepant resolutions: scenes from categorical geometry [PDF]

open access: yes, 2011
Non-commutative crepant resolutions are algebraic objects defined by Van den Bergh to realize an equivalence of derived categories in birational geometry.
