A complete locally convex space of countable dimension admitting an operator with no invariant subspaces
Stanislav Shkarin
We construct a complete locally convex topological vector space of countable algebraic dimension and a continuous linear operator such that has no non-trivial cl…
A hypercyclic finite rank perturbation of a unitary operator
Stanislav Shkarin
A unitary operator and a rank operator acting on a Hilbert space $\H$ are constructed such that is hypercyclic. This answers affirmatively a question of Salas whe…
On orbits of truncated convolution operators
Stanislav Shkarin
We prove that a semigroup generated by a finitely many truncated convolution operators on with is non-supercyclic. On the other hand, there is a truncat…
Hypercyclic tuples of operators on and
Stanislav Shkarin
A tuple of continuous linear operators on a topological vector space is called hypercyclic if there is such that the the orbit of under the actio…
Chaotic Banach algebras
Stanislav Shkarin
We construct an infinite dimensional non-unital Banach algebra and such that the sets $\{za^n:z\in\C,\ n\in\N\}$ and are both dense in ,…
The Golod-Shafarevich inequality for Hilbert series of quadratic algebras and the Anick conjecture
Natalia Iyudu, Stanislav Shkarin
We study the question on whether the famous Golod-Shafarevich estimate, which gives a lower bound for the Hilbert series of a (noncommutative) algebra, is attained. This question w…
