ABSTRACT
In this paper, we present some new perturbation bounds for subunitary polar factors in a special unitarily invariant norm called a Qâ€“norm. Some recent results in the Frobenius norm and the spectral norm are extended to the Qâ€“norm on one hand. On the other hand we also present some relative perturbation bounds for subunitary polar factors.

Using analytic methods of finite-gap integration, we construct quasihomogeneous algebraic solutions of the WDVV associativity equations and the nonsemisimple Frobenius manifolds associated with them.

In this paper, we prove that singularities of F-injective type are Du Bois. This extends the correspondence between singularities associated to the minimal model program and singularities defined by the action of Frobenius in positive characteristic.

In this paper we characterize the compact weighted Frobenius - Perron operator PÏ†u on LÂ¹(âˆ‘) and determine its spectra. Also, it is shown that every weakly compact weighted Frobenius-Perron operator on LÂ¹(âˆ‘) is compact.

The space of Frobenius manifolds has a natural involutive symmetry on it: there exists a map I which sends a Frobenius manifold to another Frobenius manifold. Also, from a Frobenius manifold one may construct a so-called almost dual Frobenius manifold which satisfies almost all of the axioms of...

This is a note on Abrams' paper "Modules, Comodules, and Cotensor Products over Frobenius Algebras, Journal of Algebras" (1999). With the application of Frobenius coordinates developed recently by Kadison, one has a direct proof of Abrams' characterization for Frobenius algebras in terms of...
