Abstract
Let {\$}\backslashSym{\^{}}m X{\$} denote the {\$}m{\$}-th symmetric power of a smooth projective curve {\$}X{\$}. Let {\$}\backslashwt{\{}\backslashSym{\^{}}m X{\}}{\$} be the blow up of {\$}\backslashSym{\^{}}m X{\$} along some non-singular subvariety. In this note we are going to discuss when the pushforward homomorphism induced by the natural morphism from {\$}\backslashwt{\{}\backslashSym{\^{}}m X{\}}{\$} to {\$}\backslashSym{\^{}}n X{\$} is injective at the level of Chow groups for {\$}m\backslashleq n{\$}. Also we are going to prove that base changes of embeddings of one symmetric power into another, with respect to closed embeddings induces an injection at the level of Chow groups.
