We combine a method of L. Panaitopol with some techniques for nonar-chimedean absolute values to provide a new proof for an irreducibility criterion of Perron for multivariate polynomials over an arbitrary field.
We present several methods to produce irreducible multivariate poly-nomials, starting from sufficiently large prime numbers.
7. The irreducibility of polynomials that have one large coefficient and take a prime value, 8. On the irreducibility of polynomials with leading coefficient divisible by a large prime power,
The effect of the pH on the ionic transfer of glycine and beta-alanine at the interface between two immiscible electrolyte solutions (ITIES) was investigated by a simple potentiometric method. Upon addition of small amounts of solution containing the investigated amino acids, a variation of the potential drop across the interface was recorded, which was… (More)
In a series of recent papers, Bonciocat et al., have shown that the faradaic current density of an electrode redox reactions occurring with combined limitations, of charge transfer and nonstationary linear, semi-infinite diffusion, is the solution of an integral equation of Volterra type. This integral equation has been transformed to describe the transport… (More)
