yuhaocsc 2018-8-25 07:56: Dear Professor He, I am so sorry to disturb you again. The last message has some mistake in format. Thus I send message again. Please forgive me. I am studying the optimal control recently. But there is a concept about conjugate point confused me. Fortunately, this concept is mentioned in your paper--“J.V.

yafeiguo 2018-5-25 18:00: Dear Professor He, I used to follow your blog since ten years ago. It was like a window to look out, to imagine what it would be to do research in the U.S. I went to Brown University as a visiting scholar last year. Now when I read your former blogs again, I find so many familiar things. I am writing to say thank you. Thanks for keep writing blogs here. Thanks for providing so many new things to Chinese young researchers including me. Best regards.
