Zeros of a cross-product of the Coulomb wave and Tricomi hypergeometric functions [PDF]

, 2016
Motivated by a problem on conditions for the existence of clines in genetics, we show that the positive zeros of a cross-product of the regular Coulomb wave function and the Tricomi hypergeometric function are increasing with respect to one of the ...

Fermionic quantum cosmology as a framework for resolving type IV singularities

European Physical Journal C: Particles and Fields
In this paper, we present an innovative approach to resolving type IV singularities in fermionic quantum cosmology. The Eisenhart–Duval lift procedure is employed to construct an extended minisuperspace metric, which allows for the formulation of the ...

Turan Type Inequalities for Tricomi Confluent Hypergeometric Functions

, 2013
Some sharp two-sided Turan type inequalities for parabolic cylinder functions and Tricomi confluent hypergeometric functions are deduced. The proofs are based on integral representations for quotients of parabolic cylinder functions and Tricomi confluent
