A fast algorithm for reversion of power series

http://www.fredrikj.net/math/reversion.html

A fast algorithm for reversion of power series. Final submitted version (PDF). To appear in Mathematics of Computation. ArXiv preprint: http:/ arxiv.org/abs/1108.4772. Published August 24, 2011; revised November 30, 2013. We give an algorithm for reversion of formal power series, based on an efficient way to implement the Lagrange inversion formula. Our algorithm requires $O(n {1/2}(M(n) M! M(n {1/2}) )$ operations where $M(n)$ and $M! This algorithm is implemented in FLINT. Back to fredrikj.net.

Evaluating parametric holonomic sequences using rectangular splitting

http://www.fredrikj.net/math/rectangular_splitting.html

Evaluating parametric holonomic sequences using rectangular splitting. Pp 256-263, DOI: 10.1145/2608628.2608629. ArXiv preprint: http:/ arxiv.org/abs/1310.3741. Published October 15, 2013. Rectangular splitting has little overhead and can perform better than either naive evaluation or asymptotically faster algorithms for ranges of $n$ encountered in applications. As an example, fast numerical evaluation of the gamma function is investigated. Our work generalizes two previous algorithms of Smith.

I was active for several years in the Doom community. Modding the classic id Software game). My best-known creations are the Vrack. Series, three maps once notorious for their size and level of detail ( Vrack. 2, released in 2001, made it onto Doomworld's list of the top 100 WADs of all time. Besides designing several maps, I wrote Omgifol. A Python library for Doom WAD files. I originally started this wiki, but no longer edit regularly). I participated in several of Doomworld's speedmapping events.

Mina politiska och fritids blogg med kommentarer och tankar om livet i stort. Fredag 14 oktober 2011. Skyddsjakt på varg eller? Efter de senaste får och lamm dödandet av varg i Fläckebo trakterna så borde man göra en insatts och ta bort några av vargarna i Skulltuna reviret. Så skyddsjakt borde ske i detta område. Sen återstår det verkliga problemet, VARFÖR har vargen börjat att gå in i våra samhällen. Måndag 10 oktober 2011. Nikotin fri i en månad nu, tänk att man kan bli det av att läsa en bra bok.

Du kan nu följa mig på min nya hemsida www.teamfigge.se. Nytt år på ingång! Senast jag skrev var det november och jag hade varit på elitträff med Rehns BK. Sen dess har jag försökt hålla igång träningen på en bra nivå för att jag ska kunna dra igång riktigt med vinterträningen efter nyår. Men jag har haft lite krångel med min fot, där det är en nerv som är lite irriterad och jag får känslan av att jag klämmer den medans jag springer. Efter 25-manna har det inte skrivits mycket här på bloggen. Men det...

Weekend in San Francisco. Som rubriken lyder. Imorgon bar det av mot San Franscisco via Highway 101. En vag som tydligen ar varldens vackraste kustvag. Fa se om den lever upp till forvantningarna. Vaskan har packats med Mamiyan, Canon AE1, ljusmatare samt en hel del Tri-x film. Ett stativ far aven det folja med. Looking forward to spend some days up there. Forsta skolveckan ar aven den avklarad. Har gatt riktigt bra. Men snart ses vi igen. Nagra manader kvar bara. 2010-09-04 @ 10:36:56 Permalink. Helgen ...

Fredrik in the U.S

So, long time no see good folk out there. I started school yesterday, at Cimarron Memorial High School. Home of the Spartans! For those who didn't know, I play for the JV soccer team. First day at school was pretty boring. We didn't learn anything. We just signed stuff. Second day, today, was better. Changed my schedule. Here is my schedule:. 2 PreCalc Honors with Mr. Vollan. He speaks Norwegian which is amazing. He happens to be the football coach and he Roar Lie's sarcasm. So I'm back from the family v...

Som Jarl ser det

Som Jarl ser det. En pysventil, varken mer eller mindre. Fredag, april 14, 2006. Oj vad inaktiv jag varit. Har väl egentligen inte så himla mycket att skylla på. Skulle vara husköp, renovering, förlorat bredband, föräldraledighet och möjligen även nytt jobb. Fast det håller inte ändå. Skall försöka bättra mig. Har nyligen börjat som politisk redaktör på Hudiksvalls tidning. Ta gärna en titt i nättidningen. Posted by Fredrik Jarl at 3:23 em. Fredag, juli 08, 2005.

Ja, da var det en stund siden jeg skrev her, grunnet litt mangel på tid, å at enkelte innlegg skrevet fra en ekstern kilde ikke gikk igjennom. Men så er jeg her igjen =). I den siste tiden har Jeg og E vært på leting etter ny leilighet, samt en liten addisjon til den lille familien vår, og for 2 uker siden fikk vi ny leilighet, og for en uke siden, fikk vi vår lille Ozzy.
