Toric varieties, monoid schemes and cdh descent
(de Gruyter, 2013-04)
We give conditions for the Mayer-Vietoris property to hold for the algebraic K-theory of blow-up squares of toric varieties in any characteristic, using the theory of monoid schemes. These conditions are used to relate ...
On the relative projective space
(R. Rosebrugh, 2019-02)
Let (C, ⊗, 1) be an abelian symmetric monoidal category satisfying certain exactness conditions. In this paper we define a presheaf P n C on the category of commutative algebras in C and we prove that this functor is a ...
Primitive to non-primitive BCH codes: An instantaneous path shifting scheme for data transmission
(World Scientific Publ Co Pte Ltd, 2018-12-01)
In this paper, we present constructions of primitive and non-primitive BCH codes using monoid rings over the local ring Z(2m), with m >= 1. We show that there exist two sequences {C-bjn}(j >= 1). and {C'(bjn)}(j >= 1) of ...
The K-theory of toric varieties in positive characteristic
(London Math Soc, 2014-03)
We show that if X is a toric scheme over a regular ring containing a field of finite characteristic, then the direct limit of the K-groups of X taken over any infinite sequence of non-trivial dilations is homotopy invariant. ...
The K-theory of toric schemes over regular rings of mixed characteristic
(Springer, 2018)
We show that if X is a toric scheme over a regular commutative ring k then the direct limit of the K-groups of X taken over any infinite sequence of nontrivial dilations is homotopy invariant. This theorem was previously ...
The existential theory of equations with rational constraints in free groups is PSPACE-complete
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005-11-01)
It is well-known that the existential theory of equations in free groups is decidable. This is a celebrated result of Makanin which was published 1982. Makanin did not discuss complexity issues, but later it was shown that ...
