Convexity properties of gradient maps associated to real reductive representations

, 2019
Let G be a connected real reductive Lie group acting linearly on a finite dimensional vector space V over R. This action admits a Kempf-Ness function and so we have an associated gradient map.

Isometry-invariant geodesics and the fundamental group, II

, 2017
We show that on a closed Riemannian manifold with fundamental group isomorphic to $\mathbb{Z}$, other than the circle, every isometry that is homotopic to the identity possesses infinitely many invariant geodesics.

Nucleotide Frequencies in Human Genome and Fibonacci Numbers [PDF]

, 2006
This work presents a mathematical model that establishes an interesting connection between nucleotide frequencies in human single-stranded DNA and the famous Fibonacci's numbers. The model relies on two assumptions.

The First Study of Mersenne--Leonardo Sequence

Communications in Advanced Mathematical Sciences
In this study, we introduce a new class of numbers, referred to as Modified Mersenne--Leonardo numbers. The aim of this paper is to define the Modified Mersenne--Leonardo sequence and investigate some of its properties, including the recurrence relation,

The Spiritual Nature of the Italian Renaissance [PDF]

, 2020
This study seeks to investigate the influence of faith in the emergence and development of the Italian Renaissance, in both the artwork and writing of the major artists and thinkers of the day, and the impact that new expressions of faith had on the ...

On some identities for the DGC Leonardo sequence [PDF]

Notes on Number Theory and Discrete Mathematics
In this study, we examine the Leonardo sequence with dual-generalized complex (DGC) coefficients for 𝔭∈ℝ. Firstly, we express some summation formulas related to the DGC Fibonacci, DGC Lucas, and DGC Leonardo sequences.

A note on a bivariate Leonardo sequence [PDF]

Notes on Number Theory and Discrete Mathematics
Recently, quite a few generalizations of Leonardo numbers have emerged in the literature. In this short note, we propose a new bivariate extension and provide its generating function.

A forma matricial dos números de Leonardo

Ciência e Natura, 2020
In this work we will investigate the generating matrices for the positive integers of the Leonardo sequence, as well as some inherent properties of these matrices. In order to perform the process of generalizing the matrix form of Leonardo’s numbers, the extension to the field of non-positive integers is performed, in which the study of these matrices ...

Chern classes of Schubert cells and varieties

, 2006
We give explicit formulas for the Chern-Schwartz-MacPherson classes of all Schubert varieties in the Grassmannian of $d$-planes in a vector space, and conjecture that these classes are effective.
