Visit to US and Germany
I have visited Rutgers University, Brown University, and University of Giessen from March 11 to 21. Because of the cancellation and the delay of my flight, I returned to Japan on 23.
I have obtained several perspectives on functional differential equations, and I am sure that this visit enables me to cultivate my research.
Finally, I acknowledge the financial support by Top Global University Project.
East asia forum
I participated "2015 East Asian Core Doctoral Forum on Mathematics'', and returned to Japan from Taiwan today. This forum was good opportunity of considering the future works.
