Problem: From the 9th century, the Pecheneg nomads began an uneasy relationship with Kievan Rus. For over two centuries they launched sporadic raids into the lands of Rus, which sometimes escalated into full-scale wars (such as the 920 war on the Pechenegs by Igor of Kiev reported in the Primary Chronicle), but there were also temporary military alliances (e.g. the 943 Byzantine campaign by Igor). In 968, the Pechenegs attacked and besieged the city of Kiev. Some speculation exists that the Pechenegs drove off the Tivertsi and the Ulichs to the regions of the upper Dniester river in Bukovina. The Byzantine Empire was known to support the Pechenegs in their military campaigns against the Eastern Slavic states.[citation needed]
What did the Pecheneg frequesntly do over the span of two centuries?

Answer: sporadic raids into the lands of Rus

Problem: Sub- and quotient groups are related in the following way: a subset H of G can be seen as an injective map H G, i.e. any element of the target has at most one element that maps to it. The counterpart to injective maps are surjective maps (every element of the target is mapped onto), such as the canonical map G G / N.y["] Interpreting subgroup and quotients in light of these homomorphisms emphasizes the structural concept inherent to these definitions alluded to in the introduction. In general, homomorphisms are neither injective nor surjective. Kernel and image of group homomorphisms and the first isomorphism theorem address this phenomenon.
What two forms must homomorphisms take?

Problem: The Miami area has a unique dialect, (commonly called the "Miami accent") which is widely spoken. The dialect developed among second- or third-generation Hispanics, including Cuban-Americans, whose first language was English (though some non-Hispanic white, black, and other races who were born and raised the Miami area tend to adopt it as well.) It is based on a fairly standard American accent but with some changes very similar to dialects in the Mid-Atlantic (especially the New York area dialect, Northern New Jersey English, and New York Latino English.) Unlike Virginia Piedmont, Coastal Southern American, and Northeast American dialects and Florida Cracker dialect (see section below), "Miami accent" is rhotic; it also incorporates a rhythm and pronunciation heavily influenced by Spanish (wherein rhythm is syllable-timed). However, this is a native dialect of English, not learner English or interlanguage; it is possible to differentiate this variety from an interlanguage spoken by second-language speakers in that "Miami accent" does not generally display the following features: there is no addition of // before initial consonant clusters with /s/, speakers do not confuse of /d/ with /j/, (e.g., Yale with jail), and /r/ and /rr/ are pronounced as alveolar approximant [] instead of alveolar tap [] or alveolar trill [r] in Spanish.
