Topological Aspects of Infinitude of Primes in Arithmetic Progressions

of rational primes. We extend results about the infinitude of prime or maximal ideals related to the Dirichlet theorem on the infinitude of primes from Knopfmacher points for the set of primes an...

A Note on Density and the Dirichlet Condition

Motivated by topological approaches to Euclid and Dirichlet's theorems on infinitude of primes, we introduce and study S-coprime topologies on a commutative ring R with an identity and without zero divisors. For infinite se...

Baťa primes

A new class of prime numbers - Baťa primes - is introduced. A positive integer is called a Baťa prime of class k if it ends with at least k 9s. We prove that for any positive integer k there exist infinitely many Baťa p...

Fredholm's third theorem for second-order singular Dirichlet problem

Consider the singular Dirichlet problem u'' = p(t)u + q(t); u(a) = 0, u(b) = 0, where p, q : ]a, b[?R are locally Lebesgue integrable functions. It is proved that if b a (s - a)(b - s)[p(s)] - ds < + and b a (s - a)(b - s) ! q(s) ! ds < +, t...

Positive solutions of the Dirichlet problem with state-dependent functional differential equations

Existence results for positive solutions of a state-dependent singular functional differential equation satisfying the Dirichlet boundary conditions are given. Results are proved by regularization and sequential techniques and use the Leray-...
