Abstract
We study a modification of the fractional analogue of the Brownian meander, which is Brownian motion conditioned to be positive on the time interval . More precisely, we determine the weak limit of a fractional Brownian motion which is penalized -- instead of being killed -- when leaving the positive half-axis. In the Brownian case, we give a representation of the limiting process in terms of an explicit SDE and compare it to the SDE fulfilled by the Brownian meander.
