Let $p$ be a prime with $pgeq 7$ and $q=2(p-1)$. In this paper we prove the existence of a nontrivial product of filtration $s+4$ in the stable homotopy groups of spheres. This nontrivial product is shown to be represented up to a nonzero scalar by the product element $widetilde{gamma}_{s}b_{n-1}g_{0}in {Ext}_{mathcal{A}}^{s+4,(p^n+sp^2+sp+s)q+s-3}(mathbb{Z}/p,mathbb{Z}/p)$ in ...
in this paper, we give some necessary conditions for a complex difference equation of malmquist type $$sum^n_{j=1}f(z+c_j)=frac{p(f(z))}{q(f(z))},$$ where $n(in{mathbb{n}})geq{2}$, and $p(f(z))$ and $q(f(z))$ are relatively prime polynomials in $f(z)$ with small functions as coefficients, admitting a meromorphic function of finite order. moreover, the properties of finite o...
خم های بیضوی و رتبه آن ها نقش مهمی در سیستم های رمزنگاری ایفا می کنند. تعیین رتبه جزء مسائل پیچیده بوده و تاکنون هیچ الگوریتم کلی برای حل آن ارائه نشده است. در این پایان نامه ابتدا الگوریتم ساده ای برای محاسبه رتبه ی خم های بیضوی خاص ارائه می دهیم که معادله آن ها در زیر آمده است. $ e:~y^{2}=x^{3}-npx $، که در آن $ n=1 $ یا $ n=2 $ و...
assume that $mathbb{d}$ is the open unit disk. applying ozaki's conditions, we consider two classes of locally univalent, which denote by $mathcal{g}(alpha)$ and $mathcal{f}(mu)$ as follows begin{equation*} mathcal{g}(alpha):=left{fin mathcal{a}:mathfrak{re}left( 1+frac{zf^{prime prime }(z)}{f^{prime }(z)}right)
In this paper, we give some necessary conditions for a complex difference equation of Malmquist type $$sum^n_{j=1}f(z+c_j)=frac{P(f(z))}{Q(f(z))},$$ where $n(in{mathbb{N}})geq{2}$, and $P(f(z))$ and $Q(f(z))$ are relatively prime polynomials in $f(z)$ with small functions as coefficients, admitting a meromorphic function of finite order. Moreover, the properties of finite o...
let $l$ be a completely regular frame and $mathcal{r}l$ be the ring of continuous real-valued functions on $l$. we show that the lattice $zid(mathcal{r}l)$ of $z$-ideals of $mathcal{r}l$ is a normal coherent yosida frame, which extends the corresponding $c(x)$ result of mart'{i}nez and zenk. this we do by exhibiting $zid(mathcal{r}l)$ as a quotient of $rad(mathcal{r}l)$, the ...
Motivated by recent results of Tao–Ziegler [Discrete Anal. 2016] and Greenfeld–Tao (2022 preprint) on concatenating affine-linear functions along subgroups an abelian group, we show three recovering affine linearity $$f: V \rightarrow W$$ from their restrictions to lines, where V, W are $${\mathbb {F}}$$ -vector spaces $$\dim \geqslant 2$$ . First, if < |{\mathbb {F}}|$$ {\mathbb is when restri...
