... 4 A I. I NTRODUCTION AND BACKG ROUND A Superconducting Integrated Receiver (SIR) [1] comprises on one chip a low-noise SIS mixer with quasioptical antenna, an Flux-Flow Oscillator (FFO) acting as a Local Oscillator (LO) and a second SIS harmonic mixer (HM) for the FFO phase locking (see Fig. ... In the SIR the bandwidth is determined by the SIS mixer tuning structure and the matching circuitry between the SIS and the FFO. ...

Summary of the pro ject by A. Shlapunov "The Cauchy Problem for Elliptic Complexes" It is well known, that the Cauchy problem for elliptic equations is ill-posed in all the standard functional spaces. ... For overdetermined elliptic systems this approach was based on Integral Representation Method. ... Differential complexes appear as compatibility conditions for overdetermined systems of differential equations (such as, for example, Maxwell system or multidimensional Cauchy-Riemann system). ...
