We provide an analogue of Strebel's classification geodesic triangles in classical $C'(\frac16)$ groups for given by Wise's cubical presentations satisfying sufficiently strong metric small cancellation conditions. Using our classification, we prove that, except specific degenerate cases, such are acylindrically hyperbolic.
We show the complete cancellation of gauge and gravitational anomalies in the Mtheory of Horava and Witten using their boundary contribution, and a term coming from the existence of two and five-branes. A factor of three discrepancy noted in an earlier work is resolved. We end with a comment on flux quantization. e-mail: [email protected] In the M-theory of Horava and Witten [1] sever...
By a paramedial groupoid we mean a groupoid satisfying the equation xy · zu = uy · zx. As it is easy to see, the equational theory of paramedial groupoids, as well as the equational theory based on any balanced equation, is decidable. In this paper we are going to investigate the equational theory of paramedial cancellation groupoids; by this we mean the set of all equations satisfied by parame...
Active cancellation stealth is a significant developing direction in modern stealth technology field. In this paper, according to characteristics of linear frequency modulated (LFM) signal and nonlinear frequency modulated (NLFM) signal, the cancellation signal was designed. An important parameter called cancellaty which is used to measure the effect of cancellation is proposed. The basic theor...
