Three families of matrices

Alexander Pushnitski

This paper has an expository nature. We compare the spectral properties (such as boundedness and compactness) of three families of semi-infinite matrices and point out similarities…

Spectral asymptotics for a family of arithmetical matrices and connection to Beurling primes

Titus Hilberdink, Alexander Pushnitski

We consider the family of arithmetical matrices given explicitly by $E = {\frac{[ n , m ] ^{t}}{( nm ) ^{(ρ + t) /2}}}_{n, m = 1}^{\infty}$ where $[n, m]$ is the least common multiple of…
