Classification of asexual diploid organisms by means of strongly isotopic evolution algebras defined over any field
(Elsevier, 2017-02-15)
Evolution algebras were introduced into Genetics to deal with the mechanism of inheritance of asexual organisms. Their distribution into isotopism classes is uniquely related with the mutation of alleles in nonMendelian ...

A Hopf theorem for open surfaces in product spaces
(De Gruyter, 2009)
Hopf’s theorem has been recently extended to compact genus zero surfaces with constant mean curvature H in a product space Mk 2 ×R, whereMk 2 is a surface with constant Gaussian curvature k = 0 [AbRo]. It also has ...

Two scenarios on a potential smoothness breakdown for the three-dimensional Navier-Stokes equations
(Cornell University, 2018)
In this paper we construct two families of initial data being arbitrarily large under any scaling-invariant norm for which their corresponding weak solution to the three-dimensional Navier- Stokes equations become smooth ...

Interpolation of Vector Measures
(Springer, 2011)
Let (Ω, Σ) be a measurable space and m 0: Σ → X 0 and m 1: Σ → X 1 be positive vector measures with values in the Banach Köthe function spaces X 0 and X 1. If 0 < α < 1, we define a new vector measure [m 0, m 1] α with ...

Complete minimal surfaces in R3 with a prescribed coordinate function
(Elsevier, 2011)
In this paper we construct complete simply connected minimal surfaces with a prescribed coordinate function. Moreover, we prove that these surfaces are dense in the space of all minimal surfaces with this coordinate ...

Polynomial graph invariants from homomorphism numbers
(Elsevier, 2016)
We give a new method of generating strongly polynomial sequences of graphs, i.e., sequences (Hk) indexed by a tuple k = (k1, . . . , kh) of positive integers, with the property that, for each fixed graph G, there is a ...

Two-hidden-layer feed-forward networks are universal approximators: A constructive approach
(ScienceDirect, 2020-11)
It is well-known that artificial neural networks are universal approximators. The classical existence result proves that, given a continuous function on a compact set embedded in an n-dimensional space, there exists a ...

Distributing persistent homology via spectral sequences
(Springer, 2023-09-20)
We set up the theory for a distributed algorithm for computing persistent homology. For this purpose we develop linear algebra of persistence modules. We present bases of persistence modules, together with an operation ...

The path-variance problem on tree networks
(Elsevier, 2004)
Extensive facility location models on graphs deal with the location of a special type of subgraphs such as paths, trees or cycles and can be considered as extensions of classical point location models. Variance is one of ...

Recent advances on Tsagas-Sourlas-Santilli isotopology
(Kyungnam University Press, 2005)
Because the Lie Theory solely applies to linear systems, in 1978 Santilli proposed the isotopic lifting of Lie’s theory for nonlinear systems, today known as the Lie-Santilli isotheory, via the reconstruction of linearity ...
