Existence and Non-existence of Fisher-KPP Transition Fronts
Existence Non-existence Fisher-KPP
2015/7/14
We consider Fisher-KPP-type reaction-diffusion equations with spatially inhomogeneous reaction rates. We show that a sufficiently strong localized inhomogeneity may prevent existence of transition-fro...
A note on non-existence of (8,4)-2 Burst error correcting code
Perfect codes Burst-error Parity-check matrix
2010/9/26
This paper presents the non-existence of (8,4)-2 burst error correcting perfect code over GF(2). An (n,k) linear code is said to be perfect if for some positive integer b, it corrects all b and fewer ...
On non-existence of some (1,2)-optimal codes
Optimal codes Burst-error Parity-check matrix
2010/9/26
This paper presents the non-existence of certain blockwise burst error correcting (1,2)-Optimal linear codes over GF(q) (q is a prime) where the code length n is divided into two sub-blocks of lengths...

We consider Fisher-KPP-type reaction-diffusion equations with spatially inhomogeneous re-
action rates. We show that a sufficiently strong localized inhomogeneity may prevent existence of transition-...
