at home, at her home, in her home, in the home

[joham]

OALD 6th edition,
1. discover:
She was discovered dead at her home in Leeds.
2. home:
Oh, no, I left my purse at home.
3. redraw:
to redraw the boundaries between male and female roles in the home

My questions are:
a. Can we replace "at her home" with "at home" or "in her home" in sentence 1?
b. Can we say "Oh, no, I left my purse at my home/ in my home"?
c. Can we say "to redraw the boundaries between male and female roles at the home/ at home"?

b. Can we say "Oh, no, I left my purse at my home/ in my home"? No.
c. Can we say "to redraw the boundaries between male and female roles at the home/ at home"? No - in this case it is a collocation expressing the general sense of "within the household".
