Sentence examples for groups of spheres from inspiring English sources
I will describe computer-checked proofs of some basic results in algebraic topology, including calculations of homotopy groups of spheres and Eilenberg-MacLane spaces.
Both groups of spheres were cultured at 37 °C with 21% O2 and 5% CO2 and the cell state was recorded at day 1, 3 and 5. SPSS 19.0 was used for the statistical analysis, and the data were presented as the mean±standard deviation.

Tables of homotopy groups of spheres are most conveniently organized by showing πn+k(Sn).
For n ≤ k+1, the groups are called the unstable homotopy groups of spheres.
He was among the first to master the technology of spectral sequences and used it, along with Henri Cartan and Jean-Pierre Serre independently in France, to initiate a systematic calculation of the homotopy groups of spheres--still a touchstone in the subject.
Scanning probe microscopic (SPM) image of optimum CC cinnamon oil NE (NE-4) shown in (Fig. 11) depicted a group of spheres have minimum interparticulate contact and generally optimal properties.
The fact that the third stable homotopy group of spheres is cyclic of order 24, first proved by Vladimir Rokhlin, implies Rokhlin's theorem that the signature of a compact smooth spin 4-manifold is divisible by 16.
More precisely, there is an injective map\Theta_n / bP_{n+1} \to \pi_n^S / J, \,\ where bPn+1 is the cyclic subgroup represented by homotopy spheres that bound a parallelizable manifold, πnS is the nth stable homotopy group of spheres, and J is the image of the J-homomorphism.
