Eigenvalue equations from the field of theoretical chemistry and correlation calculations
Sandor Kristyan
Many equations have been introduced and derived by the author indicated in the title in relation to multi-electron densities between the Hohenberg-Kohn theorems and variational pri…
Analytic evaluation of Coulomb integrals for one, two and three-electron distance operators, , and with
Sandor Kristyan
The state of the art for integral evaluation is that analytical solutions to integrals are far more useful than numerical solutions. We evaluate certain integrals analytically that…
Generalization of Brillouin theorem for the non-relativistic electronic Schrödinger equation in relation to coupling strength parameter, and its consequences in single determinant basis sets for configuration interactions
Sandor Kristyan
The Brillouin theorem has been generalized for the extended non-relativistic electronic Hamiltonian (Hkin+ Hne+ aHee) in relation to coupling strength parameter (a), as well as for…
On the statistical distribution of prime numbers, a view from where the distribution of prime numbers is not erratic
Sandor Kristyan
Currently there is no known efficient formula for primes. Besides that, prime numbers have great importance in e.g., information technology such as public-key cryptography, and the…
