Operator with the Kato property on Banach spaces
We consider a class of bounded linear operators between Banach spaces, which we call operators with the Kato property, that includes the family of strictly singular operators between those spaces. We show that if $T:E\to F$ is a dense-range operator with that property and $E$ has a separable quotient, then for each proper dense operator range $R\subset E$ there exists a closed subspace $X\subset E$ such that $E/X$ is separable, $T(X)$ is dense in $F$ and $R+X$ is infinite-codimensional. If $E^*…

Gravitational Wave Signals in a Promising Realization of SO(10) Unification
We investigate gravitational wave signals in a non-supersymmetric grand unified model where the group $SO(10)$ is broken in two steps to the Standard Model gauge group. We calculate the analytical form of the one-loop effective potential responsible for the first step of symmetry breaking and show that it can lead to a first-order phase transition with gravitational wave production. We also determine the gravitational wave background produced by the primordial plasma of relativistic particles. …
