The phrase "a theoretical study of three" is correct and usable in written English.
It can be used in academic or research contexts when discussing a study that focuses on three specific subjects, concepts, or cases.
Example: "This paper presents a theoretical study of three major theories in cognitive psychology."
Alternatives: "an analytical examination of three" or "a conceptual analysis of three".

Abrams [21] demonstrated in a theoretical study a similar divergence of traits in two prey to result from indirect evolutionary interaction mediated through a shared predator.
The objective of this work, based on a theoretical study is to investigate the energy efficiency of two components of a solar drying unit (collector, stock), which aims to satisfy a design already made for a well-defined energy needs: dry a quantity of product for a given day of the harvest season with a heat storage that relays the night.
A theoretical study is presented dealing with the immobilization of two enzymes into a porous solid support.
