Dear *friends*
Many monts ago,i searched a lot the book of Robin Harte "invertibility and singularity".
this book contains a lot of demonstrations that i need in my master. it focus on banach algebras,boundaries,connected hulls. It seems to be very helpfull.
I did not find it for free .
Is there someone who can share me a link to download it for free?
Every help will be appreciated.
