Effective differential Nullstellensatz for ordinary DAE systems with constant coefficients
(Academic Press Inc Elsevier Science, 2014-10)
We give upper bounds for the differential Nullstellensatz in the case of ordinary systems of differential algebraic equations over any field of constants K of characteristic 0. Let x be a set of n differential variables, ...
Differential equations with natural matrices coefficients
(IOP Publishing, 2020)
In this paper we present the main results of the master thesis in applied mathematics
of the second named author, which was supervised by the first named author. Such results, and
for instance this paper, concerns to ...
Comment on “Generalized differential transform method to differential-difference equation” by L. Zou et al.
(Elsevier Science, 2021-08)
We show that the differential transform is the well known Taylor series (contrary to what the authors claim) and that the differential transform method (DTM) is the well known Frobenius method, commonly used to obtain exact ...
Gonadal Differentiation and Development in the Snouted Treefrog, Scinax fuscovarius (Amphibia, Anura, Hylidae)
(Society for the Study of Amphibians and Reptiles, 2015-09)
Accurate descriptions of gonadogenesis are necessary to have a baseline to detect abnormalities during development and to assess the time a species may be more vulnerable to the action of pesticides, endocrine disruptors, ...
Quantitative aspects of the generalized differential Lüroth's Theorem
(Academic Press Inc Elsevier Science, 2018-08-01)
Let F be a differential field of characteristic 0, t=t1,…,tm a finite set of differential indeterminates over F and G⊂F〈t〉 a differential field extension of F, generated by nonconstant rational functions α1,…,αn of total ...
