On left-invariant semi-K\'{a}hler structures on six-dimensional nilpotent nonsymplectic Lie groups
Autor: Smolentsev, N. K., Chernova, K. V.
Publikováno v: Tomsk State University Journal of Mathematics and Mechanics, 2024
It is known that there are 34 classes of six-dimensional nilpotent Lie groups, many of which admit left-invariant symplectic and complex structures. Among them there are three classes of groups on which there are no left-invariant symplectic structur

Left-invariant K\'{a}hler and semi-para-K\'{a}hler structures on some six-dimensional unsolvable Lie groups
Autor: Smolentsev, N. K., Sokolova, A. Yu
Publikováno v: Tomsk State University Journal of Mathematics and Mechanics, 2024
In this article studies questions about the existence of left-invariant K\"{a}hler and semi-para-K\"{a}hler structures on six-dimensional unsolvable Lie groups whose Lie algebras are semidirect products. According to the classification results, there

We present a new set up for resonant inelastic hard X-ray scattering at the Bernina beamline of SwissFEL with energy, momentum, and temporal resolution. The compact R=0.5 m Johann-type spectrometer can be equipped with up to 3 crystal analysers and a

Left-invariant almost para-K\'{a}hler structures on six-dimensional nilpotent Lie groups
Autor: Smolentsev, Nikolay K.
Publikováno v: Tomsk State University Journal of Mathematics and Mechanics, vol. 78, 2022
In this paper, we consider left-invariant para-complex structures on six-dimensional nilpotent Lie groups. A complete list of six-dimensional nilpotent Lie groups that admit para-K\"{a}hler structures is obtained, explicit expressions for para-comple

Meyer wavelets with scaling factor $N>2$
Autor: K., Smolentsev N., N, Podkur P.
In this paper, Meyer wavelets with an arbitrary integer scaling factor $N>2$ are defined using wavelets with multiple scaling factors $MN>2$. Expressions for frequency functions of wavelets and corresponding filters are obtained.
