Fraïssé and Ramsey properties of Fréchet spaces
Jamal K. Kawach, Jordi López-Abad
We develop the theory of Fraïssé limits for classes of finite-dimensional multi-seminormed spaces, which are defined to be vector spaces equipped with a finite sequence of seminorm…

Parametrized Ramsey theory of infinite block sequences of vectors
Jamal K. Kawach
We show that the infinite-dimensional versions of Gowers' and theorems can be parametrized by an infinite sequence of perfect subsets of $2^…

An infinite-dimensional version of Gowers' theorem
Jamal K. Kawach
We prove an infinite-dimensional version of an approximate Ramsey theorem of Gowers, initially used to show that every Lipschitz function on the unit sphere of is oscillation…
