Isometry test for coordinate transformations
, 2020 A simple scheme is developed to test whether a given coordinate transformation of the metric tensor is an isometry or not. The test can also be used to predict the time dilation caused by any type of motion for a given space-time ...

Journal of Algebra, 2000 Let \(G\) be a finite simple group, \(p\) a prime and \(P\) a Sylow \(p\)-subgroup of \(G\). Suppose that there exists a perfect isometry \(I\) between the principal \(p\)-blocks \(B\) of \(G\) and \(b\) of \(H=N_G(P)\). Moreover, suppose that \(H/O_{p'}(H)\) is a Frobenius group with kernel \(PO_{p'}(H)/O_{p'}(H)\), denote by \(\mu_1,\dots,\mu_e\) the

Archaeological Prospection, EarlyView.ABSTRACT Burial mounds are key elements of Mediterranean funerary landscapes, but in intensively cultivated coastal plains their low‐relief expression is easily obscured by ploughing, levelling and rapidly changing surface conditions, making single‐date observations unreliable.

ON RING THEORETIC QUASI-ISOMETRY INVARIANTS [PDF]
We introduce an algebraic version of the translation algebra of a group. We prove that a quasi-isometry of two finitely generated groups induces Morita equivalence of their algebraic translation ...

On Extensions of Partial Isometries
In this paper we define a notion of S-extension for a metric space and study minimality and coherence of S-extensions. We show that every S-extension can be identified with an algebraic object. We use this algebraic representation to give a complete characterization of all finite minimal S-extensions of a given finite metric space and a complete ...

On similarity of operators to isometries.
Michigan Mathematical Journal, 1992 Isometric and unitary operators being central to the theory of linear operators on Hilbert space, the problem of determining whether a given operator is similar to one of these assumes a natural importance and has been examined by various researchers since 1947, when Sz.-Nagy announced necessary and sufficient conditions for similarity to an isometry ...

Arthritis &Rheumatology, EarlyView.Objective Osteoarthritis, the leading cause of disability worldwide, disproportionately affects women, yet sex remains an overlooked determinant. This disparity stems from sex‐specific differences in injury susceptibility—a major risk factor for disease.
