Korocha
Korocha (russian: Короча) is a town and the administrative center of Korochansky District in Belgorod Oblast, Russia, located on the right bank of the Korocha River (Seversky Donets' tributary), northeast of Belgorod, the administrative center of the oblast. Population: History What is now Korocha has been known since 1638 as a small Russian fortress built as a part of the defense line between modern Belgorod, Tambov, and Ulyanovsk against the Crimean Tatars. At the time, it was the south frontier of the Tsardom of Russia. It was first named Krasny gorod na Koroche, which was then shortened to Korocha. It was granted town status in 1708. Until the early 20th century, Korocha remained the main town in the region but then it lost its importance. During World War II, Korocha was occupied by the German Wehrmacht on July 1, 1942 and freed on February 7, 1943 by the Voronezh Front of the Red Army during the Third Battle of Kharkov.

Lobachevsky Medal
The Lobachevsky Prize, awarded by the Russian Academy of Sciences, and the Lobachevsky Medal, awarded by the Kazan State University, are mathematical awards in honor of Nikolai Ivanovich Lobachevsky. History The Lobachevsky Prize was established in 1896 by the Kazan Physical and Mathematical Society, in honor of Russian mathematician Nikolai Ivanovich Lobachevsky, who had been a professor at Kazan University, where he spent nearly his entire mathematical career. The prize was first awarded in 1897. Between the October revolution of 1917 and World War II the Lobachevsky Prize was awarded only twice, by the Kazan State University, in 1927 and 1937. In 1947, by a decree of the Council of Ministers of the USSR, the jurisdiction over awarding the Lobachevsky Prize was transferred to the USSR Academy of Sciences.B. N.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war. World War II was by far the List of wars by death toll, deadliest conflict in hu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Kharkiv State University
The Kharkiv University or Karazin University ( uk, Каразінський університет), or officially V. N. Karazin Kharkiv National University ( uk, Харківський національний університет імені В. Н. Каразіна), is one of the major universities in Ukraine, and earlier in the Russian Empire and Soviet Union. It was founded in 1804 through the efforts of Vasily Karazin becoming the second oldest university in modern-day Ukraine. History Russian Empire On , the Decree on the Opening of the Imperial University in Kharkiv came into force. The university became the second university in the south of the Russian Empire. It was founded on the initiative of the local community with Vasily Karazin at the fore, whose idea was supported by the nobility and the local authorities. Count Seweryn Potocki was appointed the first supervisor of the university, the first rector being the philologist and philosopher Ivan Rizhsky. In ...

Collectivization
Collective farming and communal farming are various types of, "agricultural production in which multiple farmers run their holdings as a joint enterprise". There are two broad types of communal farms: agricultural cooperatives, in which member-owners jointly engage in farming activities as a collective, and state farms, which are owned and directly run by a centralized government. The process by which farmland is aggregated is called collectivization. In some countries (including the Soviet Union, the Eastern Bloc countries, China and Vietnam), there have been both state-run and cooperative-run variants. For example, the Soviet Union had both kolkhozy (cooperative-run farms) and sovkhozy (state-run farms). Pre-20th century history A small group of farming or herding families living together on a jointly managed piece of land is one of the most common living arrangements in all of human history, having co-existed and competed with more individualistic forms of ownership (as we ...

Even more Cossacks moved to the area during the Khmelnytsky Uprising (1648–1657) and the internecine wars in the Cossack Hetmanate (1659–1679).

Partial Differential Equation
In mathematics, a partial differential equation (PDE) is an equation which imposes relations between the various partial derivatives of a multivariable function. The function is often thought of as an "unknown" to be solved for, similarly to how is thought of as an unknown number to be solved for in an algebraic equation like . However, it is usually impossible to write down explicit formulas for solutions of partial differential equations. There is, correspondingly, a vast amount of modern mathematical and scientific research on methods to numerically approximate solutions of certain partial differential equations using computers. Partial differential equations also occupy a large sector of pure mathematical research, in which the usual questions are, broadly speaking, on the identification of general qualitative features of solutions of various partial differential equations, such as existence, uniqueness, regularity, and stability. Among the many open questions are the e ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Differential Geometry
Differential geometry is a mathematical discipline that studies the geometry of smooth shapes and smooth spaces, otherwise known as smooth manifolds. It uses the techniques of differential calculus, integral calculus, linear algebra and multilinear algebra. The field has its origins in the study of spherical geometry as far back as antiquity. It also relates to astronomy, the geodesy of the Earth, and later the study of hyperbolic geometry by Lobachevsky. The simplest examples of smooth spaces are the plane and space curves and surfaces in the three-dimensional Euclidean space, and the study of these shapes formed the basis for development of modern differential geometry during the 18th and 19th centuries. Since the late 19th century, differential geometry has grown into a field concerned more generally with geometric structures on differentiable manifolds. A geometric structure is one which defines some notion of size, distance, shape, volume, or other rigidifying str ...

Convex Geometry
In mathematics, convex geometry is the branch of geometry studying convex sets, mainly in Euclidean space. Convex sets occur naturally in many areas: computational geometry, convex analysis, discrete geometry, functional analysis, geometry of numbers, integral geometry, linear programming, probability theory, game theory, etc. Classification According to the Mathematics Subject Classification MSC2010, the mathematical discipline ''Convex and Discrete Geometry'' includes three major branches: * general convexity * polytopes and polyhedra * discrete geometry (though only portions of the latter two are included in convex geometry). General convexity is further subdivided as follows: *axiomatic and generalized convexity *convex sets without dimension restrictions *convex sets in topological vector spaces *convex sets in 2 dimensions (including convex curves) *convex sets in 3 dimensions (including convex surfaces) *convex sets in ''n'' dimensions (including co ...
