First proof of existence of arbitrary long nontrivial superpositions in the Stable Homotopy Ring
for Spheres (1959):calculation of multiplication in the most important old and new cobordismrings:
Real Orientable and Unitary --- see footnote to the item n 6 of publications about the priority
relations here; Special Unitary and Symplectic. These results are based on the developement of
algebraic and geometric technique associated with Adams
Spectral Sequence. In particular, cohomology of Hopf Coalgebras and new type ''Steenrod-like''
Operations in cohomology of Hopf
Algebras over the finite fields play fundamental role here(1959-62).
The Ring Structure of the Stable Homotopy Groups of Sheres was used to find the first proof
that The Connectivity Component of Unit in the Diffeomorphism Groups of some spheres
cannot be deformed to the orthogonal subgroup (1962-63) for n=7 and more.
Let us remind that the existence of nontrivial components was discovered by Milnor in 1956 for n=6.

New Methods of Algebraic Topology from the viewpoint of
Complex Cobordism Theory, the Adams-Novikov Spectral Sequence. Complete calculation of
the ''Steenrod'' algebra of operations as the Operator
(Heisenberg) double over the Landveber-Novikov Hopf algebra with specific
Z-structure (see the items nn 122, 152 for the latest development of algebraic aspects).
Application for the study of the stable homotopy groups of spheres. Discovery of Formal
Groups of ''Geometric Cobordisms'' (Novikov-Mischenko, 1967) and its applications: the ''Adams-type''
operations in complex cobordisms; the analog of Chern Character;
Cyclic Group actions and Fixpoint Equations, calculation of the Hirzebruch
Multiplicative Series through the Formal Group (1966-1971). Further development of algebraic structures
associated with unitary cobordisms, the fixpoint equations, 2-valued formal group (Buchstaber-Novikov, 1971)

Morse inequalities and representations of fundamental group, the jumping
subvarieties for homology groups on the representation space (the analogs of
Alexander Polinomials). Complete calculation of the generic Betti number and all Milnor-Farber
Spectral Sequence for one-dimensional representations through the Massey
Operations (1986). Von Neumann factors and Morse inequalities, the Novikov-Shubin
invariants of the Laplace-Beltrami Operators on universal covering. The Von Neumann
analog of the Reidemeister-Ray-Singer Torsion. Analog of Morse-Witten
inequalitis for smooth real vector fields and diagonalization of real fermionic
quadratic forms (1986-87). Recent results: The Exotic De Rham cohomology,differential
forms and dynamical systems: new functors and exact sequences (Novikov, 2007-2008).

Closed one-forms in the Variational Calculus (Multivalued Action
Functionals on the spaces of mappings).
Classification of the ''local'' 1-forms in the field theory
(1981-82). Nonlocal 1-forms on the spaces of
mappings of spheres in the manifolds, the Analytical
Homotopy Theory, Module Spaces in The Rational (Real) Homotopy Theory (1984-88).

Topology and Qualitative Dynamics in Physics

**
General Relativity (1972-75):**

Spacely Homogeneous Solutions for the Einstein
Equation with Hydrodynamic Energy-Momentum Tensor (Homogeneous Cosmological
Models). Full description of the nondegenerate compactification of Phase Space and
System near Cosmological Singularity. Properties of the ''Typical'' Evolution and
their dependence on the
sign of time: the mixmaster (BLKh) regime survives as a typical with
probability one for the Collapsing Universe only; it disappears for the
Expansion Process immediately; some specific set of the power-like regimes are
typical for the Expanding Universe. Strict Isotropization of the Early Universe
does not follow from the classical Einstein Equation with normal physical
energy-momentum tensor (positive energy and pressure): only weak
isotropization in the first approximation of the Hubble constants in different
directions follows from dynamics. However, the real Universe has been strictly
isotropic on the large scale as it became finally clear after the later
observations of the background radiation in the late 80s.

**

Lattice:**

Strong Magnetic Fields for the normal metals with topologically complicated Fermi Surfaces.

Right definition of the symmetry group for Quasi-Crystals (the
**Quasi-Crystallographic Groups**) was invented in 1986. Nontrivial examples for the 2D case were found with infinite rotational part= factor-group by translations (S.Novikov-A.Veselov).
This approach is different from all other authors who assumed that the rotational part is finite. This result was published later (it was included in the article of Le Thang, S.Piunikhin, V.Sadov published in the Russian Mathematical Surveys
(1993), vol. 48 n1, pp 37-100, where symmetry theory for Quasi-Cristals was developed by Piunikhin).
