Explicit geodesic flow-invariant distributions using SL2(ℝ)-representation ladders by Alvaro Alvarez-Parrilla

“…An explicit construction of a geodesic flow-invariant distribution lying in the discrete series of weight 2k isotopic component is found, using techniques from representation theory of SL2(ℝ). It is found that the distribution represents an AC measure on the unit tangent bundle of the hyperbolic plane minus an explicit singular set. …”

Recent trends in user studies: action research and qualitative methods by T.D. Wilson

“…</i> It attempted to set out what was, for the time, a novel perspective on appropriate methodologies for the study of human information seeking behaviour, focusing on qualitative methods and action research, arguing that the application of information research depended up its adoption into the managerial processes of organizations, rather than its self-evident relationship to any body of theory.…”

A Note on the Asymptotic and Threshold Behaviour of Discrete Eigenvalues inside the Spectral Gaps of the Difference Operator with a Periodic Potential by Gift Muchatibaya, Josiah Mushanyu

“…In particular, applications of the Titchmarsh-Weyl m-function theory as well as the Birman-Schwinger principle is performed to investigate the existence and behaviour of the eigenvalues of the operator H0+λWn inside the spectral gap of H0 in the limits λ↑∞ and λ↓0.…”

Spatial Competition with Entry Deterrence considering Horizontal Product Differentiations by Ai-nong Zhou

“…This paper addresses spatial competitions along with horizontal product differentiations and entry deterrence. By the dynamic game theory model about one firm and a potential entrant with different cost in a linear city, this paper finds that both the higher fixed setup cost and the higher transportation cost deter entrants. …”
