A Simple Counterexample to Kouchnirenko’s Conjecture
In the late 70’s A. Kouchnirenko posed the problem of bounding from above the number of positive real roots (that is, with positive coordinates) of a system of k polynomial equations in k variables not in function of the degrees of the polynomials (like in Bezout Theorem), but in function of the number of terms involved, and he conjectured an upper bound. Although he never wrote this conjecture...
متن کاملA Counterexample Related to Topological Sums
In this paper we construct compact metric spaces X, Y which are topologically distinct but whose topological sums X X and Y Y are homeomorphic.
متن کاملA Simple Normality Criterion Leading to a Counterexample to the Converse of the Bloch Principle
Proving a normality criterion for a family of meromorphic functions we exhibit a counterexample to the general converse of Bloch principle.
متن کاملA Haar wavelets approach to Stirling's formula
This paper presents a proof of Stirling's formula using Haar wavelets and some properties of Hilbert space, such as Parseval's identity. The present paper shows a connection between Haar wavelets and certain sequences.
