Finite Square Lattice Vertex Cover by a Baseline Set Defined With a Minimum Sublattice
Richard J. Mathar
Each straight infinite line defined by two vertices of a finite square point lattice contains (covers) these two points and a - possibly empty - subset of points that happen to be…
Atmospheric refractivity effects on mid-infrared ELT adaptive optics
S. Kendrew, L. Jolissaint, R. J. Mathar +3
We discuss the effect of atmospheric dispersion on the performance of a mid-infrared adaptive optics assisted instrument on an extremely large telescope (ELT). Dispersion and atmos…
Karhunen-Loeve Basis Functions of Kolmogorov Turbulence in the Sphere
Richard J. Mathar
The statistically independent Karhunen-Loeve modes of refractive indices with isotropic Kolmogorov spectrum of the covariance are calculated in a sphere of given radius, rendered a…
Series of Reciprocal Powers of k-almost Primes
Richard J. Mathar
Sums over inverse s-th powers of semiprimes and k-almost primes are transformed into sums over products of powers of ordinary prime zeta functions. Multinomial coefficients known f…
