KÄHLER-RICCI SOLITONS ON CERTAIN TORIC BUNDLES

open access: yes
In this paper, we shall introduce the notion of a KSM-manifold, which has the structure of a fiber bundle over an Einstein-Kähler Fano manifold whose fiber is a toric Fano manifold, and prove that every KSM-manifold admits a Kähler-Ricci ...

Generalized -Einstein 3-dimensional trans-Sasakian manifold

open access: yes, 2020
. In the present note we have introduced a new concept called generalized -Einstein manifold in a 3-dimensional trans-Sasakian manifold and have given some preliminary ideas about the same.

Manifold signal processing for MIMO communications [PDF]

open access: yes, 2009
textThe coding and feedback inaccuracies of the channel state information (CSI) in limited feedback multiple-input multiple-output (MIMO) wireless systems can severely impact the achievable data rate and reliability. The CSI is mathematically represented

Admissible para-hyper-Kähler structures on distributions of almost contact metric manifolds

open access: yesДифференциальная геометрия многообразий фигур, 2018
The concepts of an admissible (almost) para-hyper-Kähler structure are introduced. On distribution of an almost contact metric manifold, as on the total space of a vector bundle, an admissible almost para-hyper­complex structure is defined.
