Up until recently, Riemannian geometry and basic topology were not
included, even by departments or faculties of mathematics, as compulsory
subjects in a university-level mathematical education. The standard
courses in the classical differential geometry of curves and surfaces
which were given instead (and still are given in some places) have come
gradually to be viewed as anachronisms. However, there has been hitherto
no unanimous agreement as to exactly how such courses should be brought
up to date, that is to say, which parts of modern geometry should be
regarded as absolutely essential to a modern mathematical education, and
what might be the appropriate level of abstractness of their exposition.
The task of designing a modernized course in geometry was begun in 1971
in the mechanics division of the Faculty of Mechanics and Mathematics of
Moscow State University. The subject-matter and level of abstractness of
its exposition were dictated by the view that, in addition to the
geometry of curves and surfaces, the following topics are certainly
useful in the various areas of application of mathematics (especially in
elasticity and relativity, to name but two), and are therefore
essential: the theory of tensors (including covariant differentiation of
them); Riemannian curvature; geodesics and the calculus of variations
(including the conservation laws and Hamiltonian formalism); the
particular case of skew-symmetric tensors (i. e.
