Tele2

Tele2 AB is a major European telecommunications operator, with about 14 million customers in 9 countries. It serves as a fixed-line telephone operator, cable and Digital television provider, mobile phone operator, IoT and Internet service provider.

Overview

Tele2 started as a telecommunications company in Sweden in the late 1970s by the company Industriförvaltnings AB Kinnevik. In 1981, a mobile phone provider called Comvik started as an alternative mobile phone operator to Televerket (today known as TeliaSonera). The cable television provider Kabelvision AB started in 1986. Comvik changed its name to become Comviq when the company got a GSM license in 1988 and started operating in 1992.

In 1991, Sweden's first commercial ISP was started with the Swedish IP Network (SWIPnet, AS1257) by Industriförvaltnings AB Kinnevik, later known as Tele2, and in 1993 with telephone liberalisation in Sweden, Tele2 started to offer international calls.

The three companies of Comviq, Kabelvision, and Tele2 came together as the Tele2 brand on fixed-line services and Comviq on mobile services in Sweden in 1997. International growth came in the form of acquisitions in Estonia, Latvia, Russia & France. Today it serves as a major telephone company in the Nordic and Baltic nations, together as an alternative provider in many others.

Top

A top is a toy designed to be spun rapidly on the ground, the motion of which causes it to remain precisely balanced on its tip because of inertia. Such toys have existed since antiquity. Traditionally tops were constructed of wood, sometimes with an iron tip, and would be set in motion by aid of a string or rope coiled around its axis which, when pulled quickly, caused a rapid unwinding that would set the top in motion. Today they are often built of plastic, and modern materials and manufacturing processes allow tops to be constructed with such precise balance that they can be set in motion by a simple twist of the fingers and twirl of the wrist without need for string or rope.

Characteristics

The motion of a top is produced in the most simple forms by twirling the stem using the fingers. More sophisticated tops are spun by holding the axis firmly while pulling a string or twisting a stick or pushing an auger. In the kinds with an auger, an internal weight rotates, producing an overall circular motion. Some tops can be thrown, while firmly grasping a string that had been tightly wound around the stem, and the centrifugal force generated by the unwinding motion of the string will set them spinning upon touching ground.

Top (mathematics)

In the context of a module M over a ring R, the top of M is the largest semisimple quotient module of M if it exists.

For finite-dimensional k-algebras (k a field), if rad(M) denotes the intersection of all proper maximal submodules of M (the radical of the module), then the top of M is M/rad(M). In the case of local rings with maximal ideal P, the top of M is M/PM. In general if R is a semilocal ring (=semi-artinian ring), that is, if R/Rad(R) is an Artinian ring, where Rad(R) is the Jacobson radical of R, then M/rad(M) is a semisimple module and is the top of M. This includes the cases of local rings and finite dimensional algebras over fields.

Category of topological spaces

In mathematics, the category of topological spaces, often denoted Top, is the category whose objects are topological spaces and whose morphisms are continuous maps or some other variant; for example, objects are often assumed to be compactly generated. This is a category because the composition of two continuous maps is again continuous. The study of Top and of properties of topological spaces using the techniques of category theory is known as categorical topology.

N.B. Some authors use the name Top for the category with topological manifolds as objects and continuous maps as morphisms.

As a concrete category

Like many categories, the category Top is a concrete category (also known as a construct), meaning its objects are sets with additional structure (i.e. topologies) and its morphisms are functions preserving this structure. There is a natural forgetful functor

to the category of sets which assigns to each topological space the underlying set and to each continuous map the underlying function.

Éder (Portuguese footballer)

Éderzito António Macedo Lopes (born 22 December 1987), commonly known as Éder, is a Portuguese professional footballer who plays for French club Lille OSC on loan from Swansea City as a forward.

He started playing professionally in 2008 with Académica, and signed for Braga four years later. Over the course of seven seasons, he amassed Primeira Liga totals of 143 games and 38 goals.

A Portuguese international since 2012, Éder represented the country at the 2014 World Cup.

Club career

Early years

Born in Bissau, Guinea-Bissau, Éder moved to Portugal as a child, and started playing football with Associação Desportiva e Cultural da Adémia in the Coimbra District at the age of 11. He made his senior debut with F.C. Oliveira do Hospital and G.D. Tourizense, the latter in the third division and the farm team of Académica de Coimbra.

Académica

Éder made his top level debut for Académica on 24 August 2008, in a 0–1 away loss against C.F. Estrela da Amadora. He scored his first goal for the club at the end of the season, netting the Students equalizing goal in an eventual 3–1 victory over Associação Naval 1º de Maio.

Éder (Italian footballer)

Éder Citadin Martins, simply known as Éder (born 15 November 1986), is a Brazilian-born Italian professional footballer who plays as a striker for Italian club Internazionale, on loan from Sampdoria, and for the Italian national team.

A Brazilian of Italian descent, he made his debut for Italy in March 2015, and scored two goals in their successful qualification campaign for UEFA Euro 2016.

Club career

Frosinone

Éder signed for Frosinone in a co-ownership deal for a fee of €600,000 in June 2008 following a loan spell during the second half of the 2007–08 Serie B season.

Return to Empoli

Empoli bought back Éder from Frosinone in June 2009 for €2.42 million following an impressive Serie B season from the striker. He scored 4 goals in one Serie B game on 15 April 2010, two of which were penalties, in a 5–2 victory for Empoli over Salernitana.

Brescia

On 20 August 2010, he signed a 1+4 year contract with Serie A newcomers Brescia, for an undisclosed fee, meaning that Éder would join Brescia on loan for the first year. Brescia later revealed in its financial report that the loan fee was €1.8 million.
