摘  要: Abstract: We consider some semi-linear elliptic equations on n-dimensional Euclidean space with critical exponent and periodic coefficients. We establish the existence of multi-bump solutions where the centers of bumps can be placed in some lattices, including infinite lattices, in k-dimensional subspace if 2k is smaller than n-2. On the other hand, we prove that if 2k is not smaller than n-2, no such solutions exist. This is a joint work with Juncheng Wei and Haoyuan Xu.
