Topological Dynamics
In mathematics, topological dynamics is a branch of the theory of dynamical systems in which qualitative, asymptotic properties of dynamical systems are studied from the viewpoint of general topology. Scope The central object of study in topological dynamics is a topological dynamical system, i.e. a topological space, together with a continuous map (topology), continuous transformation, a continuous flow, or more generally, a transformation semigroup, semigroup of continuous transformations of that space. The origins of topological dynamics lie in the study of asymptotic properties of trajectory, trajectories of systems of Autonomous system (mathematics), autonomous ordinary differential equations, in particular, the behavior of limit sets and various manifestations of "repetitiveness" of the motion, such as periodic trajectories, recurrence and minimality, stability, non-wandering points. George Birkhoff is considered to be the founder of the field. A structure theorem for minima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wesleyan University Faculty
Wesleyan theology, otherwise known as Wesleyan–Arminian theology, or Methodist theology, is a theological tradition in Protestant Christianity based upon the ministry of the 18th-century evangelical reformer brothers John Wesley and Charles Wesley. More broadly it refers to the theological system inferred from the various sermons (e.g. the Forty-four Sermons), theological treatises, letters, journals, diaries, hymns, and other spiritual writings of the Wesleys and their contemporary coadjutors such as John William Fletcher, Methodism's systematic theologian. In 1736, the Wesley brothers travelled to the Georgia colony in America as Christian missionaries; they left rather disheartened at what they saw. Both of them subsequently had "religious experiences", especially John in 1738, being greatly influenced by the Moravian Christians. They began to organize a renewal movement within the Church of England to focus on personal faith and holiness, putting emphasis on the impo ...

University Of Pennsylvania Faculty
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in the Midd ...

1918 Births
The ceasefire that effectively ended the First World War took place on the eleventh hour of the eleventh day of the eleventh month of this year. Also in this year, the Spanish flu pandemic killed 50–100 million people worldwide. In Russia, this year runs with only 352 days. As the result of Julian to Gregorian calendar switch, 13 days needed to be skipped. Wednesday, January 31 ''(Julian Calendar)'' was immediately followed by Thursday, February 14 ''(Gregorian Calendar)''. Events World War I will be abbreviated as "WWI" January * January – 1918 flu pandemic: The "Spanish flu" ( influenza) is first observed in Haskell County, Kansas. * January 4 – The Finnish Declaration of Independence is recognized by Soviet Russia, Sweden, Germany and France. * January 8 – American president Woodrow Wilson presents the Fourteen Points as a basis for peace negotiations to end the war. * January 9 – Battle of Bear Valley: U.S. troops engage Yaqui Native Ameri ...

Graph Coloring
In graph theory, graph coloring is a methodic assignment of labels traditionally called "colors" to elements of a Graph (discrete mathematics), graph. The assignment is subject to certain constraints, such as that no two adjacent elements have the same color. Graph coloring is a special case of graph labeling. In its simplest form, it is a way of coloring the Vertex (graph theory), vertices of a graph such that no two adjacent vertices are of the same color; this is called a vertex coloring. Similarly, an ''edge coloring'' assigns a color to each Edge (graph theory), edges so that no two adjacent edges are of the same color, and a face coloring of a planar graph assigns a color to each Face (graph theory), face (or region) so that no two faces that share a boundary have the same color. Vertex coloring is often used to introduce graph coloring problems, since other coloring problems can be transformed into a vertex coloring instance. For example, an edge coloring of a graph is just ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
