THE EMBEDDING PROPERTY FOR SORTED PROFINITE GROUPS
نویسندگان
چکیده
We study the embedding property in category of sorted profinite groups. introduce a notion (SEP), analogous to for show that any group has universal SEP-cover. Our proof gives an alternative existence cover group. Also our works full subcategory groups, which is closed under taking finite quotients, fibre products, and inverse limits. also having SEP complete system whose theory -categorical -stable assumption set sorts countable.

γ = c0 + c1p+ c2p + · · · = (. . . c3c2c1c0)p, with ci ∈ Z, 0 ≤ ci ≤ p− 1, called the digits of γ. This ring has a topology given by a restriction of the product topology—we will see this below. The ring Zp can be viewed as Z/pZ for an ‘infinitely high’ power n. This is a useful idea, for example, in the study of Diophantine equations: if such an equation has a solution in the integers, then it...

We introduce the notion of a pro-fusion system on a pro-p group, which generalizes the notion of a fusion system on a finite p-group. We also prove a version of Alperin’s Fusion Theorem for pro-fusion systems.
متن کاملThe Homotopy Orbit Spectrum for Profinite Groups
Let G be a pro nite group. We de ne an S[[G]]-module to be a G-spectrum X that satis es certain conditions, and, given an S[[G]]-module X, we de ne the homotopy orbit spectrum XhG. When G is countably based and X satis es a certain niteness condition, we construct a homotopy orbit spectral sequence whose E2-term is the continuous homology of G with coefcients in the graded pro nite b Z[[G]]-mod...
متن کاملCohomology of Profinite Groups
A directed set I is a partially ordered set such that for all i, j ∈ I there exists a k ∈ I such that k ≥ i and k ≥ j. An inverse system of groups is a collection of groups {Gi} indexed by a directed set I together with group homomorphisms πij : Gi −→ Gj whenever i ≥ j such that πii = idGi and πjk ◦ πij = πik. Let H be a group. We call a family of homomorphisms {ψi : H −→ Gi : i ∈ I} compatible...

در این پایان نامه به بررسی خاصیت نقطه ثابت و خاصیت نقطه ثابت برای نیم گروههای برگشت پذیر چپ روی بعضی جبرهای باناخ از جمله جبر فوریه و جبر فوریه استیلتیس پرداخته شده است. برای مثال بیان شده است که اگر گروه یک گروه فشرده موضعی با همسایگی فشرده برای عنصر همانی که تحت درونریختی ها پایاست باشد آنگاه جبر فوریه و جبر فوریه استیلتیس دارای خاصیت نقطه ثابت برای نیم گروه های برگشت پذیر چپ است اگر و تنها ا...
