The Fejér-Dirichlet Lift: Entire Functions and -Factorization Identities
Sebastian Fuchs
A Fejér-Dirichlet lift is developed that turns divisor information at the integers into entire interpolants with explicit Dirichlet-series factorizations. For absolutely summable w…

Fejér-Kernel Prime Indicators
Sebastian Fuchs
A prime indicator is constructed by applying the Fejér identity to the sine-quotient encoder of trial division. For integers $n\ge…
