His writings on geometry included several important papers on parallel curves and surfaces.
S Sasaki, Y Muto, and K Yano have developed, since 1938,the conformal theory of curves and surfaces in a conformally connected space as well as in a Riemannian space.
Painlevé's first area of interest in mathematics was rational transformations of algebraic curves and surfaces.
His series of memoirs on the contact of curves and surfaces, contributed to the'Philosophical Transactions' of 1862and subsequent years, mainly gave him his high rank as a mathematician.
Jarnik and Landau studied the same problem for curves and surfaces other than circles.
His time for research was now limited but he still made important contributions undertaking research on infinitesimal geometry, projective geometry and the differential geometry of curves and surfaces.
In particular Le Paige studied the geometry of algebraic curves and surfaces, building on this earlier work.
His favourite topicwas differential geometry and here he discovered many properties of particular curves and surfaces.
His first book A Treatise in the Differential Geometry of Curves and Surfaces, published in 1909, was on this topic and was a development of courses he had given at Princeton for several years.
Finsler' doctoral dissertation was supervised by Carathéodory on Curves and surfaces in general spaces.
The interesting series of communications on the contact of curves and surfaces which are contained in the Philosophical Transactions of 1862and subsequent years would alone account for the high rank he obtained as a mathematician.
Influenced by Cremona, Lobachevsky, Gauss and Riemann,Beltrami contributed to work in differential geometry on curves and surfaces.
Given Petrovsky 's expertise in differential equations,the topology of algebraic curves and surfaces and mathematical physics, it is not difficult to see his influence on the direction that Oleinik's work would take.
Petrovsky's main mathematical work was on the theory of partial differential equations,the topology of algebraic curves and surfaces, and probability.
Kempe, in, summarises his mathematical contributions:The interesting series of communications on the contact of curves and surfaces which are contained in the Philosophical Transactions of 1862and subsequent years would alone account for the high rank he obtained as a mathematician.
He published Neue Theorie der Elektrodynamik in 1845 and wrote various papers with applications to algebraic curves and surfaces over the next ten years.
Petrovsky's main mathematical work was on the theory of partial differential equations,the topology of algebraic curves and surfaces, and probability. Petrovsky also worked on the boundary value problem for the heat equationand this was applied to both probability theory and work of Kolmogorov.
Much of the volume is devoted to subjects to which the author has himself contributed in the last few years,particularly in the theory of families of curves and surfaces, and of small deformations.
After his 1893 treatise he published many other texts,the most important of which are Lectures on the differential geometry of curves and surfaces(1912), Lectures introductory to the theory of functions of two complex variables(1914), Calculus of variations(1927), Geometry of four dimensions which was in two volumes and published in 1930, and Intrinsic geometry of ideal space also in two volumes, published in 1935.
Studied exclusively the conformal properties of a Riemannian space itself and paid only slight attention to the conformal properties of curves and surfaces immersed in a Riemannian space.
He taught many courses at the University of Halle including: linear partial differential equations; calculus of variations; theory of elliptical functions; synthetic geometry; hydrostatics and capillarity theory;theory of space curves and surfaces; analytic mechanics; potential theory and spherical harmonics; celestial mechanics; the theory of the map projections; hydrodynamics; and the partial differential equations of mathematical physics.
Among the topics Sasaki contributed to over a long research career were Lie geometry of circles, conformal connections, projective connections, holonomy groups, Hermitian manifolds, geometry of tangent bundles and almost contact manifolds(now called Sasaki manifolds),global problems on curves and surfaces in various spaces.
Yet I must now admit that my devotion to this one branch of mathematics has been in some degree unfortunate; for time has shown(what might perhaps have been foreseen) that the elementary algebraic methods, so effective and so admirable when applied to the simpler curves and surfaces, fail to produce results when applied to loci of higher order.
Hodge, reviewing the second volume, wrote: Much of the volume is devoted to subjects to which the author has himself contributed in the last few years,particularly in the theory of families of curves and surfaces, and of small deformations.
That this is also sufficient was proved by Schouten. writers… studied exclusively the conformal properties of a Riemannian space itself and paid only slight attention to the conformal properties of curves and surfaces immersed in a Riemannian space.
As Crilly and Johnson write:Not only did he seek definitions of curve and surface, but also definitions of n-dimensional Cantorian manifoldand hence of dimension itself.
Not only did he seek definitions of curve and surface, but also definitions of n-dimensional Cantorian manifoldand hence of dimension itself.
However she essentially gave up publishing mathematics after her treatise appeared in print, except forone notable exception which was an article on Analytic geometry, curve and surface in the 14th edition of Encyclopaedia Britannica published in 1929.
