Seaver House: Built in 1900 by Pomona Valley pioneers Carlton and Estella Seaver, this house stood on the corner of Holt and Garey Avenues in the city of Pomona, California. There the Seavers raised six children, all of whom graduated from Pomona College: Georgia '04, Frank Roger '05, Byron Dick '08, Homer Carlton '11, Marguerite '14, and Nila '19.

Banach function algebras and approximate identities

Let $ K $ be a locally compact space. Then $ C_o(K) $ is the Banach algebra of all continuous,
complex-valued functions on $ K $ that vanish at infinity, taken with the pointwise algebraic
operations and uniform norm $ |\cdot|_K $. The maximal modular ideals of $ C_o(K) $ have the
form $ M_x =\{ f\in C(K) \ \colon \ f(x) = 0\} $, where $ x\in K $. We see that each of these maximal
ideals has a contractive approximate identity: this is a net $ (f_\alpha) $ in
$ M_x $ with $ |f_\alpha|_K\leqslant 1 $ and $ \lim_\alpha ff_\alpha=f $ for each $ f\in M_x $.

Now suppose that $ A $ is a Banach function algebra on $ K $ such that each maximal modular
ideal has such a contractive approximate identity. Must we have $ A=C_o(K) $? Or can you
think of such an algebra $ A $ with $ A \not= C_o(K) $? How close does the group algebra of
a locally compact group come to having the above properties?
