Semi-invariants of mixed representations of quivers
A notion of a mixed representation of a quiver can be derived from ordinary quiver representation by considering the dual action of groups on "vertex" vector spaces together with their usual action.
A generating system for the algebra of semi-invariants of mixed representations of a quiver is determined.
Implementing this point of view, Poisson Summation Formulas are proved in several spaces including integrable functions of bounded variation (where the result is known) and elements of mixed norm spaces.
A general method for a painless derivation of a dual pair of affine frames from an arbitrary MRA is obtained via the mixed extension principle.
It is shown that two new instabilities of hybrid type can occur in a rotating magnetized plasma with anisotropic pressure, i.e., the rotational firehose instability and the rotational mirror instability.
It is found that the dominant mode is a hybrid type for all pitch angles except for the case when the strips are oriented along the rod axis.
The idea of this algorithm is to optimize the free parameters of the node representation in data structure by using a hybrid type of learning algorithm.
Out of 40 regenerated plants, 37 were morphologically of a hybrid type and 3 of a cauliflower type.
The broccoli type cybrids were morphologically similar to "Green Comet", while the hybrid type was an intermediate of the two fusion parents.
