Constructions of Dense Lattices of Full Diversity
Trends in Computational and Applied Mathematics, 2020 A lattice construction using Z-submodules of rings of integers of number fields is presented. The construction yields rotated versions of the laminated lattices A_n for n = 2,3,4,5,6, which are the densest lattices in their respective dimensions.

The Algebraic Approach to Phase Retrieval and Explicit Inversion at the Identifiability Threshold [PDF]
, 2014 We study phase retrieval from magnitude measurements of an unknown signal as an algebraic estimation problem. Indeed, phase retrieval from rank-one and more general linear measurements can be treated in an algebraic way.

Splitting fields of elements in arithmetic groups
, 2011 We prove that the number of unimodular integral matrices in a norm ball whose characteristic polynomial has Galois group different than the full symmetric group is of strictly lower order of magnitude than the number of all such matrices in the ball, as ...

A Few Considerations on Structural and Logical Composition in Specification Theories [PDF]
Electronic Proceedings in Theoretical Computer Science, 2011 Over the last 20 years a large number of automata-based specification theories have been proposed for modeling of discrete,real-time and probabilistic systems. We have observed a lot of shared algebraic structure between these formalisms.

Monoidal algebraic model structures
, 2013 Extending previous work, we define monoidal algebraic model structures and give examples. The main structural component is what we call an algebraic Quillen two-variable adjunction; the principal technical work is to develop the category theory necessary

Efficient Enumeration of Higher Order Algebraic Structures
IEEE Access, 2020 Algebraic structures are widely studied mathematical structures in abstract algebra. Enumerating higher order algebraic structures is a computationally intensive task due to large number of possible permutations and the presence of many symmetrically ...

New Stable Closed Newton-Cotes Trigonometrically Fitted Formulae for Long-Time Integration
Abstract and Applied Analysis, 2012 The closed Newton-Cotes differential methods of high algebraic order for small number of function evaluations are unstable. In this work, we propose a new closed Newton-Cotes trigonometrically fitted differential method of high algebraic order which ...

Zero-dimensional families of polynomial systems
Le Matematiche, 2013 If a real world problem is modelled with a system of polynomial equations, the coefficients are in general not exact. The consequence is that small perturbations of the coefficients may lead to big changes of the solutions.
