DESCRIPTION:The origin of intermediate-mass black holes remains an open que
 stion. \nMassive and dense stellar environments are proposed as their poten
 tial birthplaces. In \nthis work\, we investigate the role of stellar colli
 sions in forming very massive stars \n(VMSs) that subsequently collapse int
 o black hole (BH) seeds. Using both direct N-body \nand Monte Carlo simulat
 ions\, our models reveal a critical mass threshold above which collisions \
 nbecome highly efficient\, allowing a significant fraction of the cluster m
 ass to be funneled \ninto a central massive object. We find that VMSs can f
 orm and collapse into BH seeds within \na few Myr in extremely dense cluste
 rs. These results support stellar collisions as a robust \npathway for earl
 y BH growth in dense environments and provide a theoretical framework for \
 ninterpreting JWST observations of compact high-redshift clusters.\n\nImpor
