“…However, transition surfaces could exist at p c,τ = 0, and such surfaces shall always separate trapped (p c,τ > 0) regions from anti-trapped (p c,τ < 0) ones. From equation (14), on the other hand, it can be seen that this becomes possible when…”

“…In parallel to the studies of LQC, loop quantum black holes (LQBHs) have also been intensively studied in the past decade or so (See, for example, [10][11][12][13][14][15] and references therein.). In particular, since the spacetime of the Schwarzschild black hole interior is homogeneous and the metric is only time-dependent, so it can be treated as the Kantowski-Sachs spacetime…”

In this brief communication, we consider the B\"ohmer-Vandersloot (BV) model of loop quantum black holes obtained from the improved dynamics approach.We adopt the Saini-Singh gauge, in which it was found analytically that the BV spacetime is geodesically complete. In this paper, we show that black/whitehole horizons do not exist in this geodesically complete spacetime. Instead, there exists only an infinite number of transition surfaces, which always separatetrapped regions from anti-trapped ones. Comments on the improved dynamics approach adopted in other models of loop quantum black holes are also given.
