In this section we outline the construction of an algebraic integrable system out of non- compact Calabi–Yau threefolds, called non-compact Calabi–Yau integrable systems, and show

For suitable representations and with respect to the bounded and weak operator topologies, it is shown that the algebra of functions with compact support is dense in the algebra

By interpreting the Hilbert series with respect to a multipartition degree of certain (diagonal) invariant and coinvariant algebras in terms of (descents of) tableaux and

We find the criteria for the solvability of the operator equation AX − XB = C, where A, B , and C are unbounded operators, and use the result to show existence and regularity

We present sufficient conditions for the existence of solutions to Neu- mann and periodic boundary-value problems for some class of quasilinear ordinary differential equations.. We

We establish Hardy-type inequalities for the Riemann-Liouville and Weyl transforms as- sociated with the Jacobi operator by using Hardy-type inequalities for a class of

Using the theory of nonlinear semigroups, we prove existence results for strong and weak solutions1. Examples are
