Władysław Ślebodziński
Władysław Ślebodziński () (February 6, 1884 – January 3, 1972) was a Polish mathematician. Władysław Ślebodziński was born in Pysznica, Poland and educated at the Jagiellonian University in Kraków (1903-1908) where he subsequently held a teaching position until 1921. After 1921, he lectured at the State High School of Mechanical Engineering Poznań and in the thirties, he was a visiting lecturer at the Poznań University and Warsaw University until 1939. During the Second World War, he gave underground lectures, leading to his imprisonment. He survived three German concentration camps: Auschwitz (1942 - 1945), where he gave underground university-level lectures as prisoner no. 79053, Gross-Rosen and Nordhausen. In 1945 he became a joint professor at Wrocław University and at the Wrocław University of Technology, and from 1951 he was a professor at the Wrocław University of Technology.

Adam Mickiewicz University In Poznań
The Adam Mickiewicz University ( pl, Uniwersytet im. Adama Mickiewicza w Poznaniu; Latin: ''Universitas Studiorum Mickiewicziana Posnaniensis'') is a research university in Poznań, Poland. It traces its origins to 1611, when under the Royal Charter granted by King Sigismund III Vasa, the Jesuit College became the first university in Poznań. The Poznań Society for the Advancement of Arts and Sciences which played an important role in leading Poznań to its reputation as a chief intellectual centre during the Age of Positivism and partitions of Poland, initiated founding of the university. The inauguration ceremony of the newly founded institution took place on 7 May 1919 that is 308 years after it was formally established by the Polish king and on 400th anniversary of the foundation of the Lubrański Academy which is considered its predecessor. Its original name was Piast University (Polish: ''Wszechnica Piastowska''), which later in 1920 was renamed to University of PoznaŠ...

Lie Derivative
In differential geometry, the Lie derivative ( ), named after Sophus Lie by Władysław Ślebodziński, evaluates the change of a tensor field (including scalar functions, vector fields and one-forms), along the flow defined by another vector field. This change is coordinate invariant and therefore the Lie derivative is defined on any differentiable manifold. Functions, tensor fields and forms can be differentiated with respect to a vector field. If ''T'' is a tensor field and ''X'' is a vector field, then the Lie derivative of ''T'' with respect to ''X'' is denoted \mathcal_X(T). The differential operator T \mapsto \mathcal_X(T) is a derivation of the algebra of tensor fields of the underlying manifold. The Lie derivative commutes with contraction and the exterior derivative on differential forms. Although there are many concepts of taking a derivative in differential geometry, they all agree when the expression being differentiated is a function or scalar field. Thus in t ...

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 structu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polish Academy Of Sciences
The Polish Academy of Sciences ( pl, Polska Akademia Nauk, PAN) is a Polish state-sponsored institution of higher learning. Headquartered in Warsaw, it is responsible for spearheading the development of science across the country by a society of distinguished scholars and a network of research institutes. It was established in 1951, during the early period of the Polish People's Republic following World War II. History The Polish Academy of Sciences is a Polish state-sponsored institution of higher learning, headquartered in Warsaw, that was established by the merger of earlier science societies, including the Polish Academy of Learning (''Polska Akademia Umiejętności'', abbreviated ''PAU''), with its seat in Kraków, and the Warsaw Society of Friends of Learning (Science), which had been founded in the late 18th century. The Polish Academy of Sciences functions as a learned society acting through an elected assembly of leading scholars and research institutions. The Academy h ...

Hugo Steinhaus
Hugo Dyonizy Steinhaus ( ; ; January 14, 1887 – February 25, 1972) was a Polish mathematician and educator. Steinhaus obtained his PhD under David Hilbert at Göttingen University in 1911 and later became a professor at the Jan Kazimierz University in Lwów (now Lviv, Ukraine), where he helped establish what later became known as the Lwów School of Mathematics. He is credited with "discovering" mathematician Stefan Banach, with whom he gave a notable contribution to functional analysis through the Banach–Steinhaus theorem. After World War II Steinhaus played an important part in the establishment of the mathematics department at Wrocław University and in the revival of Polish mathematics from the destruction of the war. Author of around 170 scientific articles and books, Steinhaus has left his legacy and contribution in many branches of mathematics, such as functional analysis, geometry, mathematical logic, and trigonometry. Notably he is regarded as one of the early found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Marczewski
Edward Marczewski (15 November 1907 – 17 October 1976) was a Polish mathematician. He was born Szpilrajn but changed his name while hiding from Nazi persecution. Marczewski was a member of the Warsaw School of Mathematics. His life and work after the Second World War were connected with Wrocław, where he was among the creators of the Polish scientific centre. Marczewski's main fields of interest were measure theory, descriptive set theory, general topology, probability theory and universal algebra. He also published papers on real and complex analysis, applied mathematics and mathematical logic. Marczewski proved that the topological dimension, for arbitrary metrisable separable space ''X'', coincides with the Hausdorff dimension under one of the metrics in ''X'' which induce the given topology of ''X'' (while otherwise the Hausdorff dimension is always greater or equal to the topological dimension). This is a fundamental theorem of fractal theory. (Certain contributions to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bronisław Knaster
BronisÅ‚aw Knaster (22 May 1893 – 3 November 1980) was a Polish mathematician; from 1939 a university professor in Lwów and from 1945 in WrocÅ‚aw. He is known for his work in point-set topology and in particular for his discoveries in 1922 of the hereditarily indecomposable continuum or pseudo-arc and of the Knaster continuum, or buckethandle continuum. Together with his teacher Hugo Steinhaus and his colleague Stefan Banach, he also developed the last diminisher procedure for fair cake cutting.

Mittelbau-Dora Concentration Camp
Mittelbau-Dora (also Dora-Mittelbau and Nordhausen-Dora) was a Nazi concentration camp located near Nordhausen in Thuringia, Germany. It was established in late summer 1943 as a subcamp of Buchenwald concentration camp, supplying slave labour from many Eastern countries occupied by Germany (including evacuated survivors of eastern extermination camps), for extending the nearby tunnels in the Kohnstein and for manufacturing the V-2 rocket and the V-1 flying bomb. In the summer of 1944, ''Mittelbau'' became an independent concentration camp with numerous subcamps of its own. In 1945, most of the surviving inmates were sent on death marches or crammed in trains of box-cars by the SS. On 11 April 1945, US troops freed the remaining prisoners. The inmates at Dora-Mittelbau were treated in a brutal and inhumane manner, working 14-hour days and being denied access to basic hygiene, beds, and adequate rations. Around one in three of the roughly 60,000 prisoners who were sent to Dora-M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
