Abstract:Abstract. Motivated by the "tug-of-war" game studied in [12], we consider a "non-local" version of the game which goes as follows: at every step two players pick respectively a direction and then, instead of flipping a coin in order to decide which direction to choose and then moving of a fixed amount > 0 (as is done in the classical case), it is a s-stable Levy process which chooses at the same time both the direction and the distance to travel. Starting from this game, we heuristically we derive a determinis… Show more
We study the Dirichlet problem for non-homogeneous equations involving the fractional p-Laplacian. We apply Perron's method and prove Wiener's resolutivity theorem.

“…For u ∈ L p−1 (R N ), x ∈ R N and ε > 0, we let (−∆) π N 2 Γ(1 − s) and Γ is the usual Gamma function (see, e.g., [5,8,9,10,11] for the linear case p = 2, and [24,25] for the general case p ∈ (1, ∞)). The fractional p-Laplacian (−∆) provided that the limit exists.…”
Abstract. Let Ω ⊂ R N be an arbitrary bounded open set. We consider a degenerate parabolic equation associated to the fractional p-Laplace operator (−∆) s p (p ≥ 2, s ∈ (0, 1)) with the Dirichlet boundary condition and a monotone perturbation growing like |τ | q−2 τ, q > p and with bad sign at infinity as |τ | → ∞. We show the existence of locally-defined strong solutions to the problem with any initial condition u 0 ∈ L r (Ω) where r ≥ 2 satisfies r > N (q − p)/sp. Then, we prove that finite time blow-up is possible for these problems in the range of parameters provided for r, p, q and the initial datum u 0 .

“…It is a generator of a strongly continuous contractive semigroup on L 2 (R n ) that can be extended to contraction semigroup on L p (R n ) for p ∈ [1, ∞] ( [3,8]). The Dirichlet boundary problem of L α,2 has been intensively investigated and many fundamental results have been proved, we refer the reader to [2,4,8,12,14] and the references therein for a fuller treatment of this topic. As a nonlinear generalization of L α,2 , L α,p has been extensively explored in recent years ( [1,5,10]).…”
For (α, p) ∈ (0, 1) × (1, ∞), this note focuses on some integrability estimates for solutions of the following Dirichlet problemwhere L α,p is the fractional p-Laplace operator.
