On regularly fibered complex surfaces
We show that a compact complex surface which fibers smoothly over a curve of genus ≥ 2 with fibers of genus ≥ 2 fibers holomorphically. We deduce an improvement of a result in [16], and a characterisation of fibered surfaces with zero signature. AMS Classification 14H15; 14J29, 20F34, 32L30, 57M50
متن کاملUpper bounds on the solutions to n = p+m^2
ardy and Littlewood conjectured that every large integer $n$ that is not a square is the sum of a prime and a square. They believed that the number $mathcal{R}(n)$ of such representations for $n = p+m^2$ is asymptotically given by begin{equation*} mathcal{R}(n) sim frac{sqrt{n}}{log n}prod_{p=3}^{infty}left(1-frac{1}{p-1}left(frac{n}{p}right)right), end{equation*} where $p$ is a prime, $m$ is a...
متن کاملDigital cohomology groups of certain minimal surfaces
In this study, we compute simplicial cohomology groups with different coefficients of a connected sum of certain minimal simple surfaces by using the universal coefficient theorem for cohomology groups. The method used in this paper is a different way to compute digital cohomology groups of minimal simple surfaces. We also prove some theorems related to degree properties of a map on digital sph...

In this paper we prove that for any hyperbolic 4-manifold M , which is R 2 bundle over surface , the absolute value of the Euler number e() of the bration : M ! is not greater than exp(exp(10 8 j(()j)). This result partially corroborates a conjecture of Gromov, Lawson and Thurston that je()j j(()j.
