Some special coprime actions and their consequences Ercan, Gülin; Güloğlu, İsmaı̇l Ş.; Kizmaz, M. Yası̇r; Revin, Danila O. (2024-12-01) Let a group A act on the group G coprimely. Suppose that the order of the fixed point subgroup CG(A) is not divisible by an arbitrary but fixed prime p. In the present paper we determine bounds for the p-length of the grou...
A search for Planet Nine with small spacecraft: Three-body, post-Newtonian, non-gravitational, planetary and Kuiper Belt effects Koprucu, Sahin Ulas; Tekin, Bayram (2024-12-01) A hypothetical gravitating body in the outer Solar System, the so-called Planet Nine, was proposed to explain the unexpected clustering of the Kuiper Belt Objects. As it has not been observed via telescopes, it was conject...
