Giuseppe Bagnera (mathematician)
Giuseppe Bagnera (14 November 1865 – 12 May 1927) was an Italian mathematician. Biography At the University of Palermo, Bagnera received his ''laurea'' in civil engineering in 1890 and then his ''laurea'' in mathematics in 1895. His teachers included Giovanni Battista Guccia, Francesco Gerbaldi ed Ernesto Cesàro. In 1899 he was appointed ''libero docente'' (lecturer) in algebraic analysis at the University of Palermo. He was appointed professor extraordinarius of infinitesimal calculus in 1901, then professor ordinarius in 1905, at the University of Messina, where he remained until the 1908 earthquake. He then taught at the University of Palermo until 1922 when he moved to the Sapienza University of Rome, where he taught until his death.Bagnera, Giuseppi — Treccani, Dizi ...

Bagheria
Bagheria (; scn, Baarìa ) is a town and ''comune'' in the Metropolitan City of Palermo in Sicily, Italy, located approximately 10km to the east of the city centre. Etymology According to some sources, the name ''Bagheria'' (by way of old Sicilian ''Baarìa'') originates from the Phoenician term ''Bayharia'' meaning "land that descends toward the sea." Other sources claim that it derives from the Arabic ''Bāb al-Gerib'', or "windy gateway." However, the most plausible explanation is that it derives from Arabic ', meaning 'of the sea, marine'. According to "Deciphering the English Code", Joseph Aronesty, the BAGH refers to a "base or bottom". Eria is just "earth" or land, from Hebrew "eretz" and many old languages. Also "area" Latin. Bagheria therefore means what it is, a land at the bottom of mountains. History Since its founding, the town has gone by the names of ''Bayharia'', ''Baharia'', and ''Baarìa''. In 1658 Giuseppe Branciforti, Prince of Butera and former Viceroy o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Academic Staff Of The University Of Palermo
An academy ( Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, '' Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

19th-century Italian Mathematicians
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Descendant Tree (group Theory)
In mathematics, specifically group theory, a descendant tree is a hierarchical structure that visualizes parent-descendant relations between isomorphism classes of finite groups of prime power order p^n, for a fixed prime number p and varying integer exponents n\ge 0. Such groups are briefly called ''finite'' ''p-groups''. The ''vertices'' of a descendant tree are isomorphism classes of finite ''p''-groups. Additionally to their ''order'' p^n, finite ''p''-groups have two further related invariants, the ''nilpotency class'' c and the coclass r=n-c. It turned out that descendant trees of a particular kind, the so-called pruned coclass trees whose infinitely many vertices share a common coclass r, reveal a repeating finite pattern. These two crucial properties of finiteness and periodicity admit a characterization of all members of the tree by finitely many parametrized presentations. Consequently, descendant trees play a fundamental role in the classification of finite ''p''-groups ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
