Rigidity of invariant complex structures [PDF]

Transactions of the American Mathematical Society, 1993
A Kähler solvmanifold is a connected Kähler manifold ( M , j , ⟨ , ⟩ ) (M,j,\left \langle , \right \rangle ) admitting a transitive solvable group of automorphisms. In this paper we study the isomorphism classes of Kähler structures (

Distribution-Robust Graph Representation Learning for Portfolio Optimization

Mathematics
Multi-asset portfolio optimization under non-stationary financial markets requires robust state representations across market phase transitions. This paper proposes distribution-robust graph representation learning for portfolio optimization (DR-GRL-PO),

Invariants of complex structures on nilmanifolds [PDF]

Archivum Mathematicum, 2015
Let $(N, J)$ be a simply connected $2n$-dimensional nilpotent Lie group endowed with an invariant complex structure. We define a left invariant Riemannian metric on $N$ compatible with $J$ to be minimal, if it minimizes the norm of the invariant part of the Ricci tensor among all compatible metrics with the same scalar curvature. In [L1], J.

Structure Is a Visual Class Invariant [PDF]

, 2008
The problem of learning the class identity of visual objects has received considerable attention recently. With rare exception, all of the work to date assumes low variation in appearance, which limits them to a single depictive style usually photographic.

The Slater and Sub-k-Domination Number of a Graph with Applications to Domination and k-Domination

Discussiones Mathematicae Graph Theory, 2020
In this paper we introduce and study a new graph invariant derived from the degree sequence of a graph G, called the sub-k-domination number and denoted subk(G).

Ultrahigh resolution and color gamut with scattering-reducing transmissive pixels

Nature Communications, 2019
Tradeoffs between size and performance have limited plasmonic structural color vibrancy at high resolution. Here the authors present a nanophotonic resonant metal-coated nanowire capable of being used as a size invariant, vibrant multicolor pixel.

PROSODIC EXPRESSION OF EMOTIONAL-AND-PRAGMATIC POTENTIAL OF A SPOKEN ENGLISH PROVERB

Novìtnâ Osvìta, 2018
The paper is a study of the prosodic features involved in the oral actualisation of English proverbs as influenced by structural, emotional and pragmatic factors, which are defined within the framework of a new energetic approach to the research of ...

SBDD-Net: Cross-Source Robust 3D Structural Block and Double Descriptor for Point Place Recognition

IEEE Access
Despite various 3D point cloud place recognition studies leveraging Pointnet, sparse convolution and graph-based methods to enhance 3D point cloud analysis, limitations persist in fully capturing the profound descriptor and ensuring domain-invariant ...
