Controllability of networks of spatially one-dimensional second order p.d.e. – an algebraic approach

For each of them describe the code: give its dimension, the number of elements, a basis, a basis of the space of linear forms vanishing on it, its minimum distance, the number of

A strong form of the Four Exponentials Conjecture states that a 2 × 2 matrix whose entries are in L e is regular, as soon as the two rows as well as the two columns are

Katzarkov-Pantev-Toen endow the schematic homotopy type with a mixed Hodge structure, Pridham extends this to the case of singular varieties, gives a Q ` analogue,. Olsson does a

However, none of these generic decoding algorithms take into account the fact that the permutation group is non-trivial, whereas it is possible to recover information on the

The Hopf algebra of rooted trees associated to Butcher’s group (as well as the Hopf algebras of planar rooted trees in [MKW08, BO05]) can be seen as a particular instance of a

Steenbrink, Mixed Hodge structure on the vanishing cohomology, in Real and Complex Singularities, Oslo 1976, ed. Varchenko, Gauss-Manin connection of isolated

and observe that the standard spectral sequence for the homology of a semisimplicial space defines a natural isomorphism.. Elements of this lattice are given by special

the classical one: assuming the local lattices Lp determine an R-module.. Any lattice in V is nonsingular at almost all p: it follows at once from the description
