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

Group theoretical derivation of Liouville action for Regge surfaces [PDF]
, 1997 We show that the structure of the Liouville action on a two dimensional Regge surface of the topology of the sphere and of the torus is determined by the invariance under the transformations induced by the conformal Killing vector fields and under ...

Tactile-Sight: A Sensory Substitution Device Based on Distance-Related Vibrotactile Flow
International Journal of Advanced Robotic Systems, 2013 Sensory substitution is a research field of increasing interest with regard to technical, applied and theoretical issues. Among the latter, it is of central interest to understand the form in which humans perceive the environment.

Some questions about the dimension of a group action [PDF]
, 2006 We discuss three families of groups, $ZW_n$, $PL(I^n)$, and $PL(S^n)$ (the last two being families of groups of piecewise-linear homeomorphisms of standard $n$-dimensional spaces).

Quantum supergroups V. Braid group action
, 2016 We construct a braid group action on quantum covering groups. We further use this action to construct a PBW basis for the positive half in finite type which is pairwise-orthogonal under the inner product.

Estimation in the group action channel
, 2018 We analyze the problem of estimating a signal from multiple measurements on a $\mbox{group action channel}$ that linearly transforms a signal by a random group action followed by a fixed projection and additive Gaussian noise.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Patient activation—encompassing knowledge, confidence, and skills in managing individual's health—is a cornerstone of person‐centered care. However, its significance among childhood, adolescent, and young adult cancer survivors (CAYACS) remains unexplored. This article examines the application of the 13‐item Patient Activation Measure (
