We provide algorithms for performing computations in generalized numerical semigroups, that is, submonoids of ℕ d with finite complement in ℕ d.These semigroups are affine semigroups, which in ...

ABSTRACT: In this paper, a spacecraft system is investigated. The system is formulated by partial differential equations with the initial and the boundary conditions. The spectral analysis and ...

Several structure theorems of such semigroups are described. This presentation is partially supported by a grant of Wu Jiehyee Charitable Foundation (HK) 2007/08. to Professor L. A. Bokut on the ...

Moreover, these solutions are Lipschitz continuous on any finite time interval and right differentiable. Our approach uses the theory of maximal monotone operators and the Crandall-Pazy theorem about ...
