L ∞ $L^{\infty }$ decay estimates of solutions of nonlinear parabolic equation
Boundary Value Problems, 2021 In this paper, we are interested in L ∞ $L^{\infty }$ decay estimates of weak solutions for the doubly nonlinear parabolic equation and the degenerate evolution m-Laplacian equation not in the divergence form. By a modified Moser’s technique we obtain L ∞

A regularized gradient flow for the p-elastic energy
Advances in Nonlinear Analysis, 2022 We prove long-time existence for the negative L2{L}^{2}-gradient flow of the p-elastic energy, p≥2p\ge 2, with an additive positive multiple of the length of the curve.

On a nonlinear degenerate evolution equation with strong damping [PDF]
International Journal of Mathematics and Mathematical Sciences, 1990 In this paper we consider the nonlinear degenerate evolution equation with strong damping, urn:x-wiley:01611712:media:ijmm603689:ijmm603689-math-0001 where K is a function with K(x, t) ≥ 0, K(x, 0) = 0 and F is a continuous real function satisfying urn:x-wiley:01611712:media:ijmm603689:ijmm603689-math-0002 Ω is a bounded domain of Rn, with smooth ...

A degenerating PDE system for phase transitions and damage [PDF]
, 2013 In this paper, we analyze a PDE system arising in the modeling of phase transition and damage phenomena in thermoviscoelastic materials. The resulting evolution equations in the unknowns \theta (absolute temperature), u (displacement), and \chi (phase ...

Large-order trend of the anomalous-dimensions spectrum of trilinear twist-3 quark operators [PDF]
, 1999 The anomalous dimensions of trilinear-quark operators are calculated at leading twist $t=3$ by diagonalizing the one-gluon exchange kernel of the renormalization-group type evolution equation for the nucleon distribution amplitude.
