New geometric constants of isosceles orthogonal type
Qi Liu, Zhijian Yang, Yongjin Li
Based on the parallelogram law and isosceles orthogonality, we define a new orthogonal geometric constant. We first discuss some basic properties of this new constant. Next, we con…

Exponential attractor for the viscoelastic wave model with time-dependent memory kernels
Yanan Li, Zhijian Yang
The paper is concerned with the exponential attractors for the viscoelastic wave model in : $$u_{tt}-h_t(0)Δu-\int_0^\infty\partial_sh_t(s)Δu(t-s)\mathrm ds+f…
