On lifting transformation groups [PDF]
Proceedings of the American Mathematical Society, 1968 It is known [1] that if (X, G, IA) is a topological transformation group such that 7r1(G) = 0, and if X is a covering space of X, then there is a unique topological transformation group (5, G, ,) which covers (X, G, IA). In [2] the fundamental group o(X, xo, G) of a group of homeomorphisms G of a topological space X is defined,, and, it is observed in ...

Synthesis of nested loop exercises for practice in introductory programming
Egyptian Informatics Journal, 2023 Novice programmers struggle to comprehend specific programming constructs such as arrays, recursion, and loops. One way to address this challenge is to provide practice problems for students in these topics that are considered difficult to comprehend ...

Amenability and Inner Amenability of Transformation Groups [PDF]
arXiv, 2020 In this paper, we show that there is a net for amenable transformation groups like F{\o}lner net for amenable groups and investigate amenability of a transformation group constructed by semidirect product of groups. We introduce inner amenability of transformation groups and characterize this property.

Quantum affine transformation group and covariant differential calculus
, 1993 We discuss quantum deformation of the affine transformation group and its Lie algebra. It is shown that the quantum algebra has a non-cocommutative Hopf algebra structure, simple realizations and quantum tensor operators.

FoxO1 signaling in B cell malignancies and its therapeutic targeting
FEBS Letters, EarlyView.FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia
FEBS Letters, EarlyView.This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

A scalar valued Fourier transform for the Heisenberg group [PDF]
arXiv, 2022 We define a scalar valued Fourier transform for functions on the Heisenberg group and establish some of its basic properties like inversion formula, Plancherel theorem and Riemann-Lebesgue lemma. We also restate certain well known theorems for the group Fourier transform in terms of the new transform which we would like to call Strichartz Fourier ...
