We present the details of a model theoretic proof of an analogue of the Manin-Mumford conjecture for semiabelian varieties in positive characteristic. As a by-product of the proof we reduce the general positive characteristic Mordell-Lang problem to a question about purely inseparable points on subvarieties of semiabelian varieties.

The use of phrasal verbs is problematic for Iranian EFL learners. Accordingly, the present studyinvestigated the performance of Iranian intermediate and advanced EFL learners in separable andinseparable verbs. The total population of the study was one hundred female Iranian EFLlearners who studied English as foreign language in Kaj language institute in Qazvin, Iran. Theparticipants were all fe...

The aim of this paper is to consider questions concerning the possible maximum cardinality various separable pseudoradial (in short: SP) spaces. most intriguing question here if there in ZFC a regular (or just Hausdorff) SP space >c. While left open, we establish number non-trivial results that list below. It consistent with MA+c=ℵ2 countably tight and compact 2c. If κ measurable cardinal then ...

the submodules with the property of the title ( a submodule $n$ of an $r$-module $m$ is called strongly dense in $m$, denoted by $nleq_{sd}m$, if for any index set $i$, $prod _{i}nleq_{d}prod _{i}m$) are introduced and fully investigated. it is shown that for each submodule $n$ of $m$ there exists the smallest subset $d'subseteq m$ such that $n+d'$ is a strongly dense submodule of $m$...

We present a theorem of Kollár on the density property of valued PAC fields and a theorem of Abraham Robinson on the model completeness of the theory of algebraically closed non-trivial valued fields. Then we prove that the theory T of non-trivial valued fields in an appropriate first order language has a model completion T̃ . The models of T̃ are non-trivial valued fields (K, v) that are ω-imper...

background: serological assay based on dense granular (gra) proteins of toxoplasma gondii (t. gondii) is actually the most popular laboratory diagnostic tool to detection of toxoplasmosis. we aimed to construct a recombinant gra7-ptz57rt plasmid vectors that it is suitable for sub-cloning and gra7 protein production. m aterials and methods: souris mice were used for maintaining of t. gondii tac...

We study the relationship between residuality of set norm attaining functionals on a Banach space and denseness operators spaces. Our first main result says that if $C$ is bounded subset $X$ which admit an LUR renorming satisfying that, for every $Y$, $T$ from to $Y$ supremum $\|Tx\|$ with $x\in C$ attained are dense, then $G_\delta$ those strongly exposes dense in $X^*$. This extends previous ...
