astro-ph0606559 | in a multiply connected space , the two twins of the special relativity twin paradox move with constant relative speed and meet a second time without acceleration . the twins situations appear to be symmetrical despite the need for one to be younger due to time dilation . here , the suggestion that the apparent symmetr... | 216 |
1309.7244 | we investigate the geometric properties of percolation clusters , by studying square - lattice bond percolation on the torus . we show that the density of bridges and nonbridges both tend to 1/4 for large system sizes . using monte carlo simulations , we study the probability that a given edge is not a bridge but has b... | 223 |
1502.03417 | for any complex number @xmath0 , let @xmath1 denote the divisor function defined by @xmath2 for all @xmath3 , and define @xmath4 to be the range of @xmath5 . we study the basic topological properties of the sets @xmath6 . in particular , we determine the complex numbers @xmath0 for which @xmath6 is bounded and determin... | 140 |
physics0008094 | in this letter recent developments are shown in experimental and theoretical physics which brings into question the validity of general relativity . this letter emphasizes the construction of a fractal @xmath0 spacetime , in @xmath1-dimensions in order to formalize a physical and consistent theory of ` quantum gravity ... | 151 |
