DESCRIPTION:Speakers: Chingkheinganba Meetei Elangbam (National Institute 
 of Technology\, Manipur\, Imphal\, India)\nWe explore the cosmological imp
 lications of Fractional Holographic Dark Energy within the context of $f(T
 )=\\beta(-T)^n$ gravity\, in which the Hubble parameter is determined impl
 icitly. The model incorporates fractional corrections through a generalize
 d entropy-area relation\, allowing for the inclusion of nonlocal effects i
 n the dark energy sector. The model parameters are optimized using Hubble 
 parameter measurements\, DES supernova data 5 year\, and BAO observations 
 for DESI DR2 via a MCMC analysis. Our results show that the model remains 
 consistent with current observational data and provides a viable cosmologi
 cal scenario. The dynamical analysis indicates that the model maintains a 
 positive energy density and a negative pressure throughout the cosmic evol
 ution\, ensuring physical consistency. The equation of state parameters ex
 hibit a quintessence-like behavior at the present epoch and gradually evol
 ve toward a cosmological constant-like phase at late times. The decelerati
 on parameter confirms a transition from deceleration to acceleration at a 
 redshift $z_t \\approx 0.78$. Furthermore\, the statefinder diagnostic rev
 eals noticeable deviations from the $\\Lambda$CDM model at intermediate re
 dshifts\, while approaching the standard fixed point $\\{r\,s\\} = \\{1\,0
 \\}$ in the asymptotic future. The estimated age of the Universe is also f
 ound to be consistent with observational constraints. Overall\, the FHDE m
 odel within $f(T)$ gravity provides a physically consistent and observatio
 nally viable description of late-time cosmic acceleration\, and may serve 
 as a promising alternative to the standard $\\Lambda$CDM paradigm.\n\nhttp
