A Lie-Theoretic Approach to the Invertibility Problem for Two-Dimensional Keller Endomorphisms Over the Real Numbers

Engineered Science
The invertibility problem for polynomial mappings is a classical topic in algebra and algebraic geometry, closely related to the Jacobian condition introduced by O. H. Keller.

Jordan Normal Forms of Endomorphisms of Vector Bundles over Curves and Applications to Moduli Space Automorphisms

Axioms
Let X be a compact connected Riemann surface of genus g≥2 and let E be a holomorphic vector bundle of rank n over X. The compactness and connectedness of X imply that the characteristic polynomial of any holomorphic endomorphism φ∈H0(X,End(E)) has ...

On Partial Groupoids Associated with the Composition of Multilayer Feedforward Neural Networks

Известия Иркутского государственного университета: Серия "Математика"
In this work, partial groupoids are constructed associated with compositions of multilayer neural networks of direct signal distribution (hereinafter simply neural networks). The elements of these groupoids are tuples of a special type. Specifying such a

Rota–Baxter Operators and Systems on Hom-π-Algebras: Constructions, Derivation Chains, and Structural Equivalence

Mathematics
(1) Background: Hom-type algebras, proposed by Yau, generalize classical algebras via twisting maps. Dendriform and tridendriform algebras, introduced by Loday and Vallette, decompose associative multiplications and play significant roles in algebraic K ...

Nielsen Type Numbers of Self-Maps on the Real Projective Plane

Fixed Point Theory and Applications, 2010
Employing the induced endomorphism of the fundamental group and using the homotopy classification of self-maps of real projective plane , we compute completely two Nielsen type numbers, (f) and (f), which estimate the number of periodic points of f ...
