A counterexample for H ∞ approximable functions
(American Mathematical Society, 2000-12)
Let D be the unit disk. We show that for some relatively closed set F ⊂ D there is a function f that can be uniformly approximated on F by functions of H∞, but such that f cannot be written as f = h + g, with h ∈ H∞ and g ...
Corrigendum to “Cluster values for algebras of analytic functions” [Adv. Math. 329 (2018) 157–173]
(Academic Press Inc Elsevier Science, 2018-04)
While the article was in publication process, we found a mistake in a key tool for the proof one of the main results. As a consequence, our result on the ball Au(BX) algebra remains open. For the algebra Hb(X) we obtain a ...
Synergistic analytical preconcentration with ionic liquid–nanomaterial hybrids
(Elsevier, 2017-12)
Nanomaterials and ionic liquids (ILs) have very attractive properties for improved analytical preconcentration methods. Thus, ILs have been used as excellent tools to functionalize nanomaterials, giving them specific ...
Analytical model of the temperature distribution in the cutting tool for orthogonal cutting process
(Joinville, SC, 2022-03-14)
This work presents an analytical model of the tool temperature distribution field for the cutting process with a new geometrical boundary assumption regarding the current models in the literature. Most of the mechanical ...
Application of factorial design and desirability function to develop a single analytical procedure for the determination of metals in different tissues of blue crab (Callinectes danae)
(2018-01-01)
In this scientific work, it was developed a single analytical procedure for the sample preparation of different tissues of blue crabs using microwave-assisted digestion for the determination of Cu, Mn, Fe and Zn by fast ...
Topological K-equivalence of analytic function-germs
(Versita, 2010-04-01)
We study the topological K-equivalence of function-germs (a"e (n) , 0) -> (a"e, 0). We present some special classes of piece-wise linear functions and prove that they are normal forms for equivalence classes with respect ...

Limits of quotients of polynomial functions in three variables
(ASSOC COMPUTING MACHINERY, 2017-06-01)
A method for computing limits of quotients of real analytic functions in two variables was developed in [4]. In this article we generalize the results obtained in that paper to the case of quotients q = f(x, y, z)/g(x, y, ...
