Jordanable almost Abelian Lie algebras

Zhirayr Avetisyan

We call a linear operator on a vector space over a field Jordanable if it has a Jordan canonical form. An almost Abelian Lie algebra has only one non-vanishing Lie bracket, which i…

Approximations in $L^{1}$ with convergent Fourier series

Zhirayr Avetisyan, Martin Grigoryan, Michael Ruzhansky

For a separable finite diffuse measure space $M$ and an orthonormal basis ${φ_{n}}$ of $L^{2} (M)$ consisting of bounded functions $φ_{n} \in L^{\infty} (M)$ ,…

The second Weyl coefficient for a first order system

Zhirayr Avetisyan, Johannes Sjoestrand, Dmitri Vassiliev

For a scalar elliptic self-adjoint operator on a compact manifold without boundary we have two-term asymptotics for the number of eigenvalues between zero and lambda when lambda te…
