A Perron Theorem for positive componentwise bilinear maps
, 2004 It is proved that a Perron type theorem holds for positive maps with bilinear components whose defining matrices satisfy a maximality assumption with respect to certain entry ratios.

Four‐Dimensional pp‐Wave Lie Groups and Harmonic Curvature
Mathematische Nachrichten, EarlyView.ABSTRACT We determine all four‐dimensional Lie groups which have harmonic curvature. In parallel, a description of four‐dimensional pp‐wave Lie groups is obtained.

A Novel Identity-based Group Signature Scheme from Bilinear Maps
, 2008 . We propose an identity-based group signature scheme from bilinear maps. The scheme has the security properties of group signatures. Our scheme is based on the CDHP assumption and bilinear maps between groups.

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14
Mathematische Nachrichten, EarlyView.ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

A Fractal Curve-Inspired Framework for Enhanced Semantic Segmentation of Remote Sensing Images
SensorsThe classification and recognition of features play a vital role in production and daily life; however, the current semantic segmentation of remote sensing images is hampered by background interference and other factors, leading to issues such as fuzzy ...

Continuity and hypocontinuity for bilinear maps
Mathematische Zeitschrift, 1984 Let E, F and G be metric linear spaces and \(b:E\times F\to G\) a separately continuous bilinear map. By employing the notion of K- convergent sequence and K-bounded sets, we give a general hypocontinuity result which holds without completeness assumptions on any of the spaces and which contains the Bourbaki hypocontinuity result for Frechet spaces as ...

Generalizations of Bilinear Maps -- Technical Report
, 2022 Bilinear maps and their classifying tensor products are well-known in the theory of linear algebra, and their generalization to algebras of commutative monads is a classical result of monad theory.

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this second part of our series of papers, we develop an abstract framework suitable for de Rham complexes that depend on a parameter belonging to an arbitrary Banach space. Our primary focus is on spectral perturbation problems and the differentiability of eigenvalues with respect to perturbations of the involved parameters. As a byproduct,
