Complexity of deep computations via topology of function spaces

Eduardo Dueñez, José Iovino, Tonatiuh Matos-Wiederhold +2

We use topological methods to study complexity of deep computations and limit computations. We use topology of function spaces, specifically, the classification of Rosenthal compac…

On the undefinability of pathological Banach spaces

Clovis Hamel, Franklin D. Tall

Motivated by Tsirelson's implicitly defined pathological Banach space, T. Gowers asked whether explicitly defined Banach spaces must include either or some . J. Iovin…

The Second-order Version of Morley's Theorem on the Number of Countable Models does not Require Large Cardinals

Franklin D. Tall, Jing Zhang

The consistency of a second-order version of a theorem of Morley on the number of countable models was proved in arXiv:2107.07636 with the aid of large cardinals. We here dispense…

A new topological generalization of descriptive set theory

Iván Ongay-Valverde, Franklin D. Tall

We introduce a new topological generalization of the -projective hierarchy, not limited to Polish spaces. Earlier attempts have replaced by , for regular uncounta…

-Theory for Model Theorists

Clovis Hamel, Franklin D. Tall

We present applications of -theory, the branch of general topology concerned with spaces of real-valued continuous functions, to model theory, mostly in the context of continu…

An undecidable extension of Morley's theorem on the number of countable models

Christopher J. Eagle, Clovis Hamel, Sandra Müller +1

We show that Morley's theorem on the number of countable models of a countable first-order theory becomes an undecidable statement when extended to second-order logic. More general…
