Imbedding free cyclic group actions in circle group actions [PDF]
Proceedings of the American Mathematical Society, 1970 Suppose a closed, orientable, irreducible 3 3 -manifold M M admits a free cyclic group action of prime order. We consider the problem of determining when M M admits an effective action of the circle group S O ( 2 ) SO(2) in which the cyclic action

Finitary Group Cohomology and Group Actions on Spheres
, 2008 We show that if G is an infinitely generated locally (polycyclic-by-finite) group with cohomology almost everywhere finitary, then every finite subgroup of G acts freely and orthogonally on some sphere.Comment: 6 ...

OPTIMAL LINE PACKINGS FROM FINITE GROUP ACTIONS
Forum of Mathematics, Sigma, 2020 We provide a general program for finding nice arrangements of points in real or complex projective space from transitive actions of finite groups. In many cases, these arrangements are optimal in the sense of maximizing the minimum distance.

Periodic Complexes and Group Actions
, 2000 In this paper we show that the cohomology of a connected CW complex is periodic if and only if it is the base space of an orientable spherical fibration with total space that is homotopically finite dimensional.

Quantum Money from Abelian Group Actions [PDF]
TheoretiCSWe give a construction of public key quantum money, and even a strengthened version called quantum lightning, from abelian group actions, which can in turn be constructed from suitable isogenies over elliptic curves.

Symmetries, group actions, and entanglement
, 2006 We address several problems concerning the geometry of the space of Hermitian operators on a finite-dimensional Hilbert space, in particular the geometry of the space of density states and canonical group actions on it.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Perception of intentionality in group actions
Journal of Human Environmental Studies, 2008 The present study examined how people explain actions performed by groups and individual members. The study specifically tested whether the presence of an executive function in groups to make decisions would affect the contents of behavior explanations ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Blinatumomab has been shown to be highly effective for patients with pediatric B‐ALL and has recently become standard of care therapy. Due to its past use in the clinical trial setting, there is limited information available about real‐world administration.

A small serving of mash: (Quantum) algorithms for SPDH-Sign with small parameters
Journal of Mathematical CryptologyWe find an efficient method to solve the semidirect discrete logarithm problem (SDLP) over finite nonabelian groups of order p3{p}^{3} and exponent p2{p}^{2} for certain exponentially large parameters. This implies an attack on SPDH-Sign,Pronounced “SPUD-
