Abstract The quasi-bicircular problem (QBCP) is a periodic time-dependent perturbation of the Earth–Moon restricted three-body (RTBP) that accounts for effect Sun. It based on using solution Earth–Moon–Sun to write equations motion infinitesimal particle. paper focuses dynamics near $$L_1$$ L 1</mml:mn...

In this paper, we introduce and study a generalized Yosida approximation operator associated to H(·, ·)-co-accretive operator and discuss some of its properties. Using the concept of graph convergence and resolvent operator, we establish the convergence for generalized Yosida approximation operator. Also, we show an equivalence between graph convergence for H(·, ·)-co-accretive operator and gen...

The Madry Lab recently hosted a competition designed to test the robustness of their adversarially trained MNIST model. Attacks were constrained to perturb each pixel of the input image by a scaled maximal L∞ distortion = 0.3. This decision discourages the use of attacks which are not optimized on the L∞ distortion metric. Our experimental results demonstrate that by relaxing the L∞ constraint ...
