Shamkhor
Shamkir ( az, Şəmkir), known historically as Annenfeld, is a city in and the capital of Shamkir District in western Azerbaijan, located in the northern foothills of the Lesser Caucasus, on the coast of the Chagirchay River on Tbilisi-Yevlakh highway, about from Dallar railway station. It is the eighth largest city in Azerbaijan by population. Etymology One theory is that the name derives from the dialectal Azerbaijani word ''sham'', meaning ''a place covered in green''.Pospelov, pp. 27–28Kotlyakoventry on "Shamkir"/ref> Population As of October 1, 2021, the population of the region was 221372 people. History In antiquity, the territory of the modern Shamkir was part of the province of Utik, a part of the Kingdom of Armenia until 387 AD. Greco-Roman historians from the 2nd century BC to the 4th century AD state that Utik was a province of Armenia, with the Kura River separating Armenia and Caucasian Albania.

Riemannian Geometry
Riemannian geometry is the branch of differential geometry that studies Riemannian manifolds, smooth manifolds with a ''Riemannian metric'', i.e. with an inner product on the tangent space at each point that varies smoothly from point to point. This gives, in particular, local notions of angle, length of curves, surface area and volume. From those, some other global quantities can be derived by integrating local contributions. Riemannian geometry originated with the vision of Bernhard Riemann expressed in his inaugural lecture "''Ueber die Hypothesen, welche der Geometrie zu Grunde liegen''" ("On the Hypotheses on which Geometry is Based.") It is a very broad and abstract generalization of the differential geometry of surfaces in R3. Development of Riemannian geometry resulted in synthesis of diverse results concerning the geometry of surfaces and the behavior of geodesics on them, with techniques that can be applied to the study of differentiable manifolds of higher dim ...

University Of Tartu Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

Yerevan State University Alumni
Yerevan ( , , hy, Երևան , sometimes spelled Erevan) is the capital and largest city of Armenia and one of the world's oldest continuously inhabited cities. Situated along the Hrazdan River, Yerevan is the administrative, cultural, and industrial center of the country, as its primate city. It has been the capital since 1918, the fourteenth in the history of Armenia and the seventh located in or around the Ararat Plain. The city also serves as the seat of the Araratian Pontifical Diocese, which is the largest diocese of the Armenian Apostolic Church and one of the oldest dioceses in the world. The history of Yerevan dates back to the 8th century BCE, with the founding of the fortress of Erebuni in 782 BCE by King Argishti I of Urartu at the western extreme of the Ararat Plain. Erebuni was "designed as a great administrative and religious centre, a fully royal capital." By the late ancient Armenian Kingdom, new capital cities were established and Yerevan declined in impo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kazan
Kazan ( ; rus, Казань, p=kɐˈzanʲ; tt-Cyrl, Казан, ''Qazan'', IPA: ɑzan is the capital and largest city of the Republic of Tatarstan in Russia. The city lies at the confluence of the Volga and the Kazanka rivers, covering an area of , with a population of over 1.2 million residents, up to roughly 1.6 million residents in the urban agglomeration. Kazan is the fifth-largest city in Russia, and the most populous city on the Volga, as well as the Volga Federal District. Kazan became the capital of the Khanate of Kazan and was conquered by Ivan the Terrible in the 16th century, becoming a part of Russia. The city was seized and largely destroyed during Pugachev's Rebellion of 1773–1775, but was later rebuilt during the reign of Catherine the Great. In the following centuries, Kazan grew to become a major industrial, cultural and religious centre of Russia. In 1920, after the Russian SFSR became a part of the Soviet Union, Kazan became the capital of the Tat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moscow State Pedagogical University
Moscow State Pedagogical University or Moscow State University of Education is an educational and scientific institution in Moscow, Russia, with eighteen faculties and seven branches operational in other Russian cities. The institution had undergone a series of name changes since its establishment in 1872. History The university originates in the Moscow Higher Courses for Women founded by Vladimir Guerrier in 1872. It was subsequently reconstituted several times. In 1918 it admitted men and became the Second Moscow State University, then was reformed without its Medical and Chemical Technology schools as the Moscow State Pedagogical Institute, which for a time was known as the Moscow State V. I. Lenin Pedagogical Institute. In 1990, the Institute regained the status of university and thus its present name. Guerrier Courses (1872–1888) In May 1872 the Russian Minister of Education, Count Dmitry Tolstoy, consented to the opening by Professor Guerrier of " Higher Women's Cours ...

Riemannian Symmetric Space
In mathematics, a symmetric space is a Riemannian manifold (or more generally, a pseudo-Riemannian manifold) whose group of symmetries contains an inversion symmetry about every point. This can be studied with the tools of Riemannian geometry, leading to consequences in the theory of holonomy; or algebraically through Lie theory, which allowed Cartan to give a complete classification. Symmetric spaces commonly occur in differential geometry, representation theory and harmonic analysis. In geometric terms, a complete, simply connected Riemannian manifold is a symmetric space if and only if its curvature tensor is invariant under parallel transport. More generally, a Riemannian manifold (''M'', ''g'') is said to be symmetric if and only if, for each point ''p'' of ''M'', there exists an isometry of ''M'' fixing ''p'' and acting on the tangent space T_pM as minus the identity (every symmetric space is complete, since any geodesic can be extended indefinitely via symmetries about t ...

Submanifold
In mathematics, a submanifold of a manifold ''M'' is a subset ''S'' which itself has the structure of a manifold, and for which the inclusion map satisfies certain properties. There are different types of submanifolds depending on exactly which properties are required. Different authors often have different definitions. Formal definition In the following we assume all manifolds are differentiable manifolds of class ''C''''r'' for a fixed , and all morphisms are differentiable of class ''C''''r''. Immersed submanifolds An immersed submanifold of a manifold ''M'' is the image ''S'' of an immersion map ; in general this image will not be a submanifold as a subset, and an immersion map need not even be injective (one-to-one) – it can have self-intersections. More narrowly, one can require that the map be an injection (one-to-one), in which we call it an injective immersion, and define an immersed submanifold to be the image subset ''S'' together with a topology and differentia ...
