Elliptic curve hidden number problem
WebWe exhibit a quantum algorithm for determining the zeta function of a genus g curve over a finite field Fq, which is polynomial in g and log(q) This amounts to giving an algorithm to produce provably random elements of the class group of a curve, plus a recipe for recovering a Well polynomial from enough of its cyclic resultants. The latter effectivizes a … WebApr 13, 2024 · σ min and s u shown in Equation (1) can be obtained by solving the undrained compression problem of the 2D elliptic cavity. As shown in Figure 8 , the bubble is idealized as an elliptical cavity with the horizontal axis radius a and vertical axis radius c existing in anisotropic saturated matrix.
