AI中文摘要:
我们研究在不稳定范围m≥n下,S^{2m+1}上主SU(n)丛的规范群同伦类型计数这一经典问题,通过计算特定p-局部Samelson乘积,得到这类同伦类型数的下界,同时讨论了最后一个稳定情形。
英文摘要:
We explore the classical question of enumerating the homotopy types of gauge groups of principal $\mathrm{SU}(n)$-bundles over $S^{2m+1}$ in the unstable range $m\geq n$. Using computations of certain $p$-local Samelson products, we obtain lower bounds on the number of such homotopy types. We also present a discussion of the last stable case.
