Ramaswamy S. Vaidyanathaswamy
Ramaswamy S. Vaidyanathaswamy (1894–1960) was an Indian mathematician who wrote the first textbook of point-set topology in India. He is notable for having been the first to discover the generalisation of the crystallographic restriction theorem to arbitrary dimensions. Life He was born in India on 24 October 1894. Vaidyanathaswamy studied Mathematics at the University of Edinburgh in Scotland, under Prof Edmund Taylor Whittaker graduating around 1914. He then did postgraduate studies at the University of Cambridge under Prof H. F. Baker. After his return to India, he was a professor at the University of Madras, and after his retirement was associated with the Indian Statistical Institute in Calcutta. He contributed extensively to point-set topology, and wrote a well-known textbook on the subject (and the first such textbook published in India), "Set Topology", which was first published in 1947. A second edition, published in 1960, was reprinted by Dover Publications in 1999 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Point-set Topology
In mathematics, general topology (or point set topology) is the branch of topology that deals with the basic set-theoretic definitions and constructions used in topology. It is the foundation of most other branches of topology, including differential topology, geometric topology, and algebraic topology. The fundamental concepts in point-set topology are ''continuity'', ''compactness'', and ''connectedness'': * Continuous functions, intuitively, take nearby points to nearby points. * Compact sets are those that can be covered by finitely many sets of arbitrarily small size. * Connected sets are sets that cannot be divided into two pieces that are far apart. The terms 'nearby', 'arbitrarily small', and 'far apart' can all be made precise by using the concept of open sets. If we change the definition of 'open set', we change what continuous functions, compact sets, and connected sets are. Each choice of definition for 'open set' is called a ''topology''. A set with a topology i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indian Mathematical Society
The Indian Mathematical Society (IMS) is the oldest organization in India devoted to the promotion of study and research in mathematics. The Society was founded in April 1907 by V. Ramaswamy Aiyer with its headquarters at Pune. The Society started its activities under the tentatively proposed name ''Analytic Club'' and the name was soon changed to ''Indian Mathematical Club''. After the adoption of a new constitution in 1910, the society acquired its present name, the Indian Mathematical Society. The first president of the Society was B. Hanumantha Rao. Publications The Society publishes two periodicals both of which are quarterly: *The ''Journal of the Indian Mathematical Society'' (''JIMS'': ISSN 0019-5839) *''The Mathematics Student'' (''Math Student'': ) The 1911 volume of the ''Journal'' contains one of the earliest contributions of the Indian mathematician Srinivasa Ramanujan.

James Hartley Ashworth
James Hartley Ashworth (2 May 1874 – 4 February 1936) was a British marine zoologist. Life See He was born on 2, May 1874, in Accrington in Lancashire, the only son of James Ashworth. He spent most of his early life in Burnley, attending the Carlton Road School there. He appears to have befriended Dr James MacKenzie during his youth, due to MacKenzie's role as the family GP, and his interest in science was awakened. MacKenzie appears to have had a mentoring role during his teenage years. Ashworth was encouraged to train, and went to Manchester to study chemistry at Owen's College. Here he quickly found a new interest and changed to study zoology. He then moved to London University where he received a BSc with Honours in Zoology and Botany in 1895. In 1899 he received a Doctorate in the same subject. He obtained a post in Naples in Italy where his interests began to focus upon marine biology. In 1901 he became a lecturer in invertebrate zoology at the University of Edinbur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

India, officially the Republic of India, is a country in South Asia. It is the List of countries and dependencies by area, seventh-largest country by area; the List of countries by population (United Nations), most populous country since 2023; and, since its independence in 1947, the world's most populous democracy.
